Abstract

The present publication is the third Section of a series being prepared in response to the

persistent need for a current revision of two sets of tables containing data on atomic spectra as derived from analyses of optical spectra. As in the first two Sections, Part A contains the atomic

energy levels and Part B the multiplet tables. All six spectra of carbon, C I through C VI are included.

The form of presentation is described in detail in the text to Section 1, and need not be repeated

here.

Key words: Atomic energy levels, carbon spectra; Atomic spectra of carbon; Carbon spectra;

Multiplet tables, carbon spectra; Spectra, carbon; Wavelengths, carbon spectra.

Foreword

The National Standard Reference Data System provides effective access to the quantitative

data of physical science, critically evaluated and compiled for convenience, and readily accessible

through a variety of distribution channels. The System was established in 1963 by action of the

President’s Office of Science and Technology and the Federal Council for Science and Technology,

with responsibility to administer it assigned to the National Bureau of Standards.

The System now comprises a complex of data centers and other activities, carried on in aca- demic institutions and other laboratories both in and out of government. The independent operational status of existing critical data projects is maintained and encouraged. Data centers that are components of the NSRDS produce compilations of critically evaluated data, critical reviews of the

state of quantitative knowledge in specialized areas, and computations of useful functions derived

from standard reference data. In addition, the centers and projects establish criteria for evaluation

and compilation of data and make recommendations on needed improvements in experimental

techniques. They are normally closely associated with active research in the relevant field. The technical scope of the NSRDS is indicated by the principal categories of data compilation

projects now active or being planned: nuclear properties, atomic and molecular properties, solid state properties, thermodynamic and transport properties, chemical kinetics, and colloid and

surface properties and mechanical properties.

The NSRDS receives advice and planning assistance from the National Research Council of

the National Academy of Sciences-National Academy of Engineering. An overall Review Committee

considers the program as a whole and makes recommendations on policy, long-term planning, and

international collaboration. Advisory Panels, each concerned with a single technical area, meet

regularly to examine major portions of the program, assign relative priorities, and identify specific

key problems in need of further attention. For selected specific topics, the Advisory Panels sponsor

subpanels which make detailed studies of users’ needs, the present state of knowledge, and existing

data resources, as a basis for recommending one or more data compilation activities. This assembly

of advisory services contributes greatly to the guidance of NSRDS activities.

The NSRDS-NBS series of publications is intended primarily to include evaluated reference

data and critical reviews of long-term interest to the scientific and technical community.

Preface

The present publication is the third Section of a series that is being prepared in response to the

increasing demand for a current revision of two sets of tables containing data on atomic spectra as derived from analyses of optical spectra.

The first set. Atomic Energy Levels, NBS Circular 467, consists of three Volumes published,

respectively, in 1949, 1952, and 1958, and a fourth on rare-earth spectra, still in course of

preparation.

The second set consists of two Multiplet Tables; one published in 1945 by the Princeton University Observatory, containing spectral lines in the region of wavelengths longer than 3000 A;

the other An Ultra-Violet Multiplet Table, NBS Circular 488. appearing in five Sections, the first in 1950, the second in 1952, and the others in 1962.

Both the atomic energy levels and the multiplet table are being included in the same publication, as parts A and B, respectively. The Sections are being prepared at irregular intervals for those

spectra whose analyses are essentially complete. A flexible paging system permits the arrangement

of the various Sections by atomic number regardless of the order in which the spectra are published

in this series. Section 1 includes three spectra of silicon, Z= 14: Si II, Si III, Si iv. Section 2 contains similar data for Si I. All six spectra of carbon are included in the present Section. Details

regarding the form of presentation are described fully in the text of Section 1. All Sections are arranged identically and the same conversion factor from cm-1 to eV, 0.000123981 is used

throughout.

The manuscript has been prepared by Charlotte E. Moore of the Office of Standard Reference

Data, who has also prepared the earlier tables. She appreciates the cordial cooperation of the many

atomic spectroscopists whose work is quoted here. She has benefitted greatly from the helpful

advice of B. Edlen in Lund, and is most grateful to him and B. Lofstrand for extending the analysis

of C V especially for inclusion here. The users are also indebted to Barbara N. Somerville for her

careful work in typing the press copy of these difficult tables.

The terms are from the Monograph by L. Johansson. He has revised and greatly extended

the analysis from observations of some 450 lines in the range from 2478 A to 25843 A. He and

Litzen have classified 75 lines in the lead sulphide region, which they have used to extend the

identifications of C I in the solar spectrum.

Short of 2000 A Johansson lists calculated wavelengths to 945 A. Herzberg has measured a group of 6 lines near 1300 A that provide auxiliary standards in the near vacuum ultraviolet region.

Kaufman and Ward have extended the list of auxiliary standards by observing 18 lines between

1459 A and 1930 A. By combining these two sets of observations they derive term values that

differ from those of Johansson as follows:

2p 23F2 ,t +0.02 cm-1

3 P°, 2

3 3 D°, 2

They give the following values for the lowest levels:

3 P2 43.42

2p

2 *d2 10192.66

These observations thus confirm Johannson’s level values “to well within his stated uncertainties.”

The differences are so small that there is no reason to recalculate the wavelengths for C I. The limit is well determined from the long np 3 D3 series.

Pair-coupling notation is given in the table for the levels of the n/-configuration (n — 4 to 8). Extrapolated level values are entered in brackets. The entries for 2

The analysis is by Glad, who has reobserved the spectrum from 1987 A to 8800 A. Five lines have

o o been added between 9200 A and 9900 A from spectrograms taken by Bockasten.

o O Herzberg has remeasured two groups of C II lines, one at 1760 A and one at 1335 A. These five wavelengths provide auxiliary standards in the near vacuum ultraviolet and have been combined with

other measurements to give additional calculated standards to shorter wavelengths. They serve, also,

to improve the earlier values of the energy levels. In his 1963 paper Edlen extends the list of calculated wavelengths in the vacuum ultraviolet on

the basis of these corrected level-values, which he has generously furnished for inclusion here. The

values for the terms 2p 2 P° and 2p22 D have been improved and, in turn, lead to a correction of — 0.43

cm-1 to be applied to all other values by Glad.

o o From 438 A to 1760 A the earlier measurements by Edlen have been superseded by calculated

wavelengths based on the present list of energy levels.

The levels in the 4f and 5f configurations designated by Glad 4 D-2 i/ 2 and 2 D2 i/ 2 have been interchanged in accordance with a suggestion by Bockasten.

The limit has been determined by Bromander but is derived from Glad’s data.

The analysis is from Bockasten, who has remeasured the spectrum in the region from 1900 A to 9950 A. He has added 121 new lines and 21 new levels to the earlier results by Edlen. All terms have

been recalculated on the basis of the new observations. The ionization limit has been well determined by fitting a Ritz formula to the terms of the ng 3 G series (n — 5, 6, 7). These authors. have

furnished the revised value of the limit quoted here; it is from unpublished work by A. Olme.

Two classifications are transitions between levels that are not connected with the rest of the

term system. For this reason the uncertainty “jc” is indicated in the Table for the terms 4d' 3 F°

and 5/' 3 G, and “y” for 4

/' 3 G and 5g' 3 H°. In both cases the uncertainty is probably less than

The analysis is by Bockasten, who has observed and remeasured the spectrum from 1900 \

o to 9950 A, with the sliding spark as source, and remeasured the resonance doublet. The new

measurements combined with Edlen’s wavelengths for ten lines in the region 380 A to 1250 A have

been used to recalculate the term system. The author has, also, made a detailed study of the

Stark effect.

The term system “as obtained from the observations” is quoted in the table except for Ip 2 P°

and 7g

2 G. The theoretical or “unperturbed” term values calculated for hydrogenic terms and from

an extended Ritz formula are quoted for higher series members; these are entered in brackets.

In his 1934 Monograph, Edlen’s list of classified lines includes the additional terms of the

np 2 P° series, n= 10 and 11, and 10d 2 D. These have been included from his observations. The

higher terms have been derived from the calculated wavelengths in the 1969 reference. The

unresolved 2 P° term, 64520 cm-1

, has been used to calculate the nd 2 D terms {n = 11 to 14).

The limit is well determined from the unperturbed terms of the ns 2 S series (n = 2, 3, 4, 6).

The value as corrected by Olme is quoted.

O : In 1939 Edlen and Tyren reported observations of series in the region from 60 A to 15 A in

the vacuum spark spectra of the elements B to F. They interpreted the lines as transitions from

doubly-excited states, indicating “the existence of discrete energy levels lying above the ionization

limits by amounts up to five times the ionization potential of the same spectrum.” In a private

: communication Edlen has reported that eleven lines were measured by Tyren between 40.3 A

o and 41.5 A, near the C v resonance line. These authors conclude that the lines “must for the main

part be of the type

On the basis of a theoretical study Wu has attempted to classify some of these satellite lines.

The earlier analysis has been revised and extended by B. Edlen and B. Ldfstrand especially

for inclusion here. The terms are based on “new measurements in the region below 300 A and some

previous observations at longer wavelengths.” In deriving the term values the theoretical values

of 2p ‘P° and of the difference 2s 3 S2s ‘S have been adopted in order to fix the terms with n — 2. For n > 2 the terms “follows directly from the observations.”

The limit has been determined by adopting the theoretical ionization energy of 2p ‘P° as given

by Accad et al. The five-term series ns 3 S, np :i > 1 P° and /ic/ 3 ’*D, are represented by two-parameter

Ritz formulae. The authors have applied the polarization formula to the hydrogen-like terms in

C V and predicted the wavelengths of several hydrogen-like transitions.

All predicted terms are entered in brackets in the table.

A number of C V lines can be identified in spectra obtained from beam foil observations and

laser-produced plasma, by means of wavelengths predicted from the present term values. Edlen and

Ldfstrand report 12 such lines in their 1970 paper.

o In 1939 Edlen and Tyren observed a group of carbon lines near 34 A analogous to those of

He I interpreted as transitions of the type Is 2s—2p 2s and Is 2p~2p 2p, giving rise to energy states “extremely high above the ionization limit.” Feldman and Cohen have measured seven such lines

in a low-inductance vacuum spark spectrum, classified them as due to the above transitions and in

addition. Is 3s—2p 3s. The high levels involved lie in the range from 5300000 cm" 1 to 5800000 cm" 1

. Both the observed positions and intensities of these lines agree well with the theoretical interpretation.

In 1938 Tyren reported several members of the Lyman Series as observed, in the region 25 A

to 35 A.

The terms listed below have been calculated by J. D. Garcia and J. E. Mack as part of their

extensive calculations of H-like spectra to Ca XX. Their values refer to the isotope l2 G for which

they used the value R= 109732.29205.

Edlen has also calculated centre-of-gravity wavelengths of the Lyman lines Is — np, n — 2 to 7,

for the natural isotope mixture, but the difference is negligible in the case of C VI. REFERENCES
