Abstract

The present publication is the second Section of a series 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.

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

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 included three spectra of silicon, Z=14 : Si n, Si in, Si iv. The

present Section contains similar data for Si i. 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 ; atomic spectra Si i ; multiplet table ; silicon, first spectrum ; spectrum, Si i; wavelengths, Si i.

Foreword

The National Standard Reference Data System is a government-wide effort to give to the

technical community of the United States optimum access to the quantitative data of physical

science, critically evaluated and compiled for convenience. This program was established in

1963 by the President’s Office of Science and Technology, acting upon the recommendation of

the Federal Council for Science and Technology. The National Bureau of Standards has been

assigned responsibility for administering the effort. The general objective of the System is to coordinate and integrate existing data evaluation and compilation activities into a systematic,

comprehensive program, supplementing and expanding technical coverage when necessary,

establishing and maintaining standards for the output of the participating groups, and providing

mechanisms for the dissemination of the output as required.

The NSRDS is conducted as a decentralized operation of nation-wide scope with central

coordination by NBS. It comprises a complex of data centers and other activities, carried on in

government agencies, academic institutions, and nongovernmental laboratories. 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.

For operational purposes, NSRDS compilation activities are organized into seven categories

as listed below. The data publications of the NSRDS, which may consist of monographs, looseleaf sheets, computer tapes, or any other useful product, will be classified as belonging to one

or another of these categories. An additional “General” category of NSRDS publications will

include reports on detailed classification schemes, lists of compilations considered to be Standard

Reference Data, status reports, and similar material. Thus, NSRDS publications will appear in

the following eight categories:

Preface

The present publication is the second 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

o University Observatory, containing spectral fines in the region of wavelengths longer than 3000 A;

the other AN ULTRAVIOLET 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 I included three spectra of silicon, Z=14: Sill, Si III, Si IV. The present

Section contains similar data for Si I. The form of presentation is described in detail in the text

to Section 1, and need not be repeated here.

The manuscript has been prepared by Charlotte E. Moore of the Atomic Physics Division,

who also prepared the earlier tables. She acknowledges with gratitude the cordial cooperation of

of the National Research Council Committee on Line Spectra of the Elements, as well as that of

the many atomic spectroscopists who make such a publication possible. It is hoped that as suc- ceeding Sections appear they will provide a stimulus to carry on the analyses of many more atomic

spectra.

The analysis is chiefly from the 1965 paper by Radziemski and Andrew, supplemented by

observations in the lead sulphide region by Litzen and in the vacuum ultraviolet by these authors

and by Kaufman and Wilson. The range of observations is from 1255 A to 25854 A. There are approximately 650 classified lines.

The writer has rearranged the 6/ pairs and made other adjustments consistent with the observed combinations. Improved level values from the 1967 paper are quoted.

The limit has been derived by a modified Ritz formula from nf series, with n = 4 to 7, nd 'Tj

series with n = 3 to 8, and nd 3 D% series with n = 3 to 10. Lambert and Warner have extended the present analysis by predicting additional series

members and deriving level values from lines in the solar spectrum: nf to n = 10; nd to n=ll.

Their values have been added in proof for the levels:

6/'[lH,2

If [2 Ak corrected

If [4 Ho

Eurther confirmation of their data from laboratory observations is desirable.

The present multiplet table might well be extended to include additional predicted lines as the analysis and solar data are carried further.

THE NATIONAL BUREAU OF STANDARDS

The National Bureau of Standards1 provides measurement and technical information services

essential to the efficiency and effectiveness of the work of the Nation’s scientists and engineers. The

Bureau serves also as a focal point in the Federal Government for assuring maximum application of

the physical and engineering sciences to the advancement of technology in industry and commerce. To

accomplish this mission, the Bureau is organized into three institutes covering broad program areas of

research and services:

THE INSTITUTE FOR BASIC STANDARDS . . . provides the central basis within the United

States for a complete and consistent system of physical measurements, coordinates that system with the

measurement systems of other nations, and furnishes essential services leading to accurate and uniform

physical measurements throughout the Nation’s scientific community, industry, and commerce. This

Institute comprises a series of divisions, each serving a classical subject matter area: —Applied Mathematics—Electricity—Metrology—Mechanics—Heat—Atomic Physics—Physical

Chemistry—Radiation Physics—Laboratory Astrophysics2—Radio Standards Laboratory, 2 which

includes Radio Standards Physics and Radio Standards Engineering—Office of Standard Refer- ence Data.

THE INSTITUTE FOR MATERIALS RESEARCH . . . conducts materials research and provides

associated materials services including mainly reference materials and data on the properties of materials. Beyond its direct interest to the Nation’s scientists and engineers, this Institute yields services

which are essential to the advancement of technology in industry and commerce. This Institute is or- ganized primarily by technical fields: —Analytical Chemistry—Metallurgy—Reactor Radiations—Polymers—Inorganic Materials—Cryogenics2—Office of Standard Reference Materials.

THE INSTITUTE FOR APPLIED TECHNOLOGY . . . provides technical services to promote the use of available technology and to facilitate technological innovation in industry and government. The

principal elements of this Institute are: —Building Research—Electronic Instrumentation—Technical Analysis—Center for Computer Sci- ences and Technology—Textile and Apparel Technology Center—Office of Weights and Measures —Office of Engineering Standards Services—Office of Invention and Innovation—Office of Vehicle

Systems Research—Clearinghouse for Federal Scientific and Technical Information3—Materials

Evaluation Laboratory—NBS/GSA Testing Laboratory.
