THE NATIONAL BUREAU OF STANDARDS

Functions and Activities

The functions of the National Bureau of Standards are set forth in the Act of Congress, March

3, 1901, as amended by Congress in Public Law 619, 1950. These include the development and

maintenance of the national standards of measurement and the provision of means and methods for making measurements consistent with these standards; the determination of physical constants and

properties of materials; the development of methods and instruments for testing materials, devices,

and structures; advisory services to government agencies on scientific and technical problems; in- vention and development of devices to serve special needs of the Government; and the development

of standard practices, codes, and specifications. The work includes basic and applied research,

development, engineering, instrumentation, testing, evaluation, calibration services, and various

consultation and information services. Research projects are also performed for other government

agencies when the work relates to and supplements the basic program of the Bureau or when the

Bureau's unique competence is required. The scope of activities is suggested by the listing of

divisions and sections on the inside of the back cover. Publications

The results of the Bureau's work take the form of either actual equipment and devices or published papers. These papers appear either in the Bureau's own series of publications or in the

journals of professional and scientific societies. The Bureau itself publishes three periodicals

available from the Government Printing Office: The Journal of Research, published in four separate

sections, presents complete scientific and technical papers; the Technical News Bulletin presents

summary and preliminary reports on work in progress; and Basic Radio Propagation Predictions

provides data for determining the best frequencies to use for radio communications throughout the

world. There are also five series of nonperiodical publications: Monographs, Applied Mathematics

Series, Handbooks, Miscellaneous Publications, and Technical Notes. Information on the Bureau's publications can be found in NBS Circular 460, Publications of

the National Bureau of Standards ($1.25) and its Supplement ($1.50), available from the Superintendent of Documents, Government Printing Office, Washington 25, D.C.

New Description of Thorium Spectra

Romuald Zalubas

Wavelengths and estimated intensities in electrodeless lamp and spark sources are presented for 15121 lines of Th I, Th II, Th III, and.Th iv in the spectral range from 2000 to 11550 A. Previously published interferometric values

are in this table rounded off to three decimal places and followed by the letter i.

1. Introduction

In 1868, forty years after Berzelius' discovery of

thorium, Thalen measured the first spectral lines

of this element [1].^ Later in 1909, Moore [2] was

the first to observe the splitting of thorium lines

in a magnetic field. - Kayser in volume 6 of his

Handbuch der Spectroskopie listed 23 papers on the

thorium spectra which had appeared up to 1912.

His table contained about 1,600 arc and spark lines

of thorium. This probably constituted about half

of the total number of knowm lines, for weak lines were not included because at that time he did

not see much use for them. Since then there have

appeared about 50 more papers dealing with the

thorium spectra, some being contributions to special regions of the spectra starting in the vacuum

and ending in the infrared region; some dealing

with its identification in the solar spectrum, in chemical compounds or in radioactivity decay

products; some describing and analyzing Th i, Th II, Th III, and Th iv; and some others being

theoretical considerations of the thorium spectra

among the other rare earth spectra. Since 1912,

three new compilations have been published,

namely; in 1939, the MIT Wavelength tables [3]; in 1946, the Specola Vaticana in Die Spektren der

Seltenen Erden gave a list of the known Th i, ii,

I and III lines [4]; and in 1958, Oak Ridge National

I Laboratory published a Compilation of Data of

' some Spectra of Thorium [5]. In these four de-

' scriptions, the references to most of the literature on the thorium spectra can be found; therefore,

there is little use in giving a complete bibliography

here. As early as 1926 [6], work on the thorium spectra

at the National Bureau of Standards was initiated

by Kiess, but never published. Kiess secured some

spectrograms of arcs and sparks between thorium

' metal electrodes in air with a Hilger prism spectrograph having a dispersion of 0.6 A/mm at X2200 A. He also measured some of these spectrograms, and

these measurements are incorporated in the present publication. In 1955 the thorium program was resumed at the Bureau under the supervision of Kiess, be- cause halide electrodeless lamps excited by micro- waves at 2, 450 Ale became available. These lamps

' Figures In brackets Indicate the literature references on p. 2.

emit much sharper and more numerable lines than

conventional arcs in air and do not excite the

troublesome atmospheric bands that normally

mask selected regions of the spectrum.

The first electrodeless thorium halide (Th L and

Th Br4) lamps were made of thorium metal by

combining the metal and halogen. The metal, as

later appeared, had impurities of zirconium.

Later Bozman succeeded in making a thorium

halide lamp, by using Th O2. These spectrograms were free of zirconium impurities, thus en- abling us to eliminate the zirconium lines from our

list. The concave grating spectrographs of the

Bureau with 7,500, 15,000, and 30,000 lines per

inch were used. Spectrograms were taken with

various sources, namely with an electrodeless

lamp and with a spark having thorium metal

electrodes. They also included iron electrodeless

lamp exposures to furnish iron secondary wavelength standards.

Zeeman magnetic patterns of Th i and Th 11 have been produced by using the Bureau electro- magnet with fields of about 37,000 oersteds.

About 1,000 of these patterns have been measured

and the resulting ^/-values determined.

Th I, Th II, and Th iii lines have been separated

by using the following criteria: (a) Relative in- tensities in lamp and spark exposures; (b) relative

intensities of n and p components of unresolved

Zeeman patterns as compared with a no field ex- posure; (c) resolved Zeeman patterns; and (d)

known classified lines of Th i, Th 11, Th iii, and

Th IV from the literature [7]. Usually, lines relatively stronger in an elec- trodeless lamp than in a spark exposure are Th i lines; those relatively weak in lamp exposures and

stronger in spark exposures are Th 11 lines; and

lines either not present or very weak in lamp ex- posures but relatively strong in spark exposures

are Th iii lines. At least three sets of plates in every region

have been secured and measured by "hand and

eye." Only near the end of the work some plates were measured by semiautomatic Bureau equipment, which in turn is designed for further process- ing by electronic computers. Most of the lines have been measured on three plates, and some of

1
them on as many as eight plates. A few lines are included that have been measured only twice.

Simultaneously with this work, interferometric

measurements of thorium secondary standards in the region X3287 A—6989 A were made by Meggers

and Stanley [8] at the Bureau. Their results have

been used to improve the accuracy of our measure- ments of thorium lines. The relative intensities

of the lines in lamp exposures were first estimated

by eye, and later calibrated to a uniform scale in

the region from 2000 to 9000 A by using Corliss'

et al. [9] unpublished data of relative intensities

for 2,000 lines of thorium. Spark intensities have

not been calibrated to a uniform scale. The wavelengths are tabulated in table 1. The

first column gives the wavelength in Angstrom

units. The letter i after the wavelength indicates

the thorium standards, wavelengths of which are taken from published interferometric measure- ments [8] and rounded off to three decimal places.

This was done in order to make the list more

convenient for users of thorium standards. Our

grating wavelengths do not differ more than

±0.005 A from the corresponding interferometric

measurements. The second and the third columns

contain intensities of lines in electrodeless lamps

and sparks in air. The letter symbols are used to describe the character of the lines; d—double,

h—hazy, w—wide, I—shaded to longer wavelength, and s—shaded to shorter wavelength.

The fourth column in the table gives the assign- ? ment of the individual line to successive spectra.

Table 1 contains more than twice as many lines as have heretofore, been published. It should meet i all the present requirements for spectrochemistry,

and for an extension of the structural analysis of Th I and Th ii between the wavelength limits I 2000 and 12000 A. The work on the analysis of

Th I is continuing at this Bureau. A short ac- count of the present state of analysis of Th i has

been published separately [10].

This work could not have been carried to its present stage of completion without the cordial

collaboration of several spectroscopists. The

author is especially indebted to C. C. Kiess for suggesting the problem, for the use of his unpublished data and for taking a keen interest in the

progress of the analysis. W. F. Meggers and

R. W. Stanley generously furnished the thorium

standard wavelengths used here. W. F. Meggers

and C. H. Corliss provided the data for calibrating

the intensities of Th i lines. C. H. Corliss and

W. E. Bozman provided some of the lamps used

for sources, and the latter assisted greatly with ' the coding, printing and other digital computer

work. Mrs. Ruth Peterson has been an invaluable

assistant with the computational and clerical ,, work. To all of these it is a pleasure to record i

my gratitude.
