The Calculation of Rotational Energy Levels and Rotational Line Intensities in Diatomic Molecules
Date: June 1970
Creator: Hougen, Jon T.
Description: Report describing procedures for making quantum mechanical calculations of rotational energy levels and rotational line intensities in diatomic molecules. The procedures are illustrated by sample calculations. A familiarity with the material of this report should enable a practicing electronic spectroscropist to carry out, though in a rather mechanical way, his own theoretical calculations for molecules under experimental investigation.

Shielding Against Gamma Rays, Neutrons, and Electrons From Nuclear Weapons: A Review and Bibliography
Date: February 24, 1964
Creator: Hubbell, J. H.
Description: Report discussing the problem of predicting dose rates and of estimating the effectiveness of shielding from radiations resulting from nuclear explosions. A number of calculations and supporting experiments regarding the penetration and diffusion of gamma rays, neutrons, and electrons through air and bulk materials are summarized. Indications are given of gaps in such input information. A selection of 485 references from the unclassified literature is presented, of which 388 are cataloged as to source geometry and energy, absorber material and configuration, type of data presented, and method of calculation or experimental technique. These cataloged references include radiation field studies ranging from the point-source infinite-medium situation up through such complicated geometries as foxholes, shelters, and conventional structures. The other references are of a general or review nature or contain input spectral data.

A Gage Block Measurement Process Using Single Wavelength Interferometry
Date: December 1975
Creator: Beers, John S.
Description: Report describing the interferometric measurement process using a laser light source and a Kosters type gage block interferometer. Continuous evaluation and refinement of the process is aided by statistical treatment and control chart techniques. All error sources, both random and systematic, are evaluated and the process is maintained in a state of statistical control.

Standard X-ray Diffraction Powder Patterns: Section 2. Data for 37 Substances
Date: May 3, 1963
Creator: Swanson, Howard E.
Description: Report discussing standard X-ray diffraction powder patterns for thirty-seven substances. Eleven are to replace patterns already given in the X-ray Powder Data File issued by the American Society for Testing and Materials, and twenty-six patterns indicated by asterisks are for substances not previously included. The X-ray Powder Data File is a compilation of diffraction patterns from many sources and is used for the identification of unknown crystalline materials by matching spacing and intensity measurements. The patterns were made with a Geiger counter X-ray diffractometer, using samples of high purity.

Standard X-ray Diffraction Powder Patterns: Section 1. Data for 46 Substances
Date: March 9, 1962
Creator: Swanson, Howard E.
Description: Report discussing forty-six standard X-ray diffraction powder patterns. Fourteen are to replace twelve patterns already given in the X-ray Powder Data File, and thirty-four are for substances not previously included. The X-ray Powder Data File is a compilation of diffraction patterns from many sources and is used for the identification of unknown crystalline materials by matching spacing and intensity measurements. The patterns were made with a Geiger counter X-ray diffractometer, using samples of high purity.

Thermal Expansion of Technical Solids at Low Temperatures: A Compilation From the Literature
Date: May 19, 1961
Creator: Corruccini, Robert J.
Description: Report giving tables of the linear contraction relative to 293 ºK, (L293ºLT)/L293, and the linear expansion coefficient, dL/L293dT, of thirty elements, forty-five alloys, twenty-two other inorganic substances and twenty plastics and elastomers in the temperature range, 0 to 300 ºK.

Bibliography of Temperature Measurement: January 1953 to June 1960
Date: April 6, 1961
Creator: Halpern, Carl
Description: Report presenting more than 500 references to the field of temperature measurement. These references were collected from two general sources: Scientific and technical literature and government reports. The period covered is from 1953 to June 1960, with some from earlier dates. References are divided into a number of categories based on the type of instrument used. Some references to calibration of instruments and to scientific theories upon which temperature measurement is based are also presented.

Annotated Bibliography on Soft X-ray Spectroscopy
Date: June 29, 1962
Creator: Yakowitz, Harvey, 1939-
Description: Report presenting a bibliography of about 550 references of the soft X-ray literature since 1950 and through 1960. The emphasis is on the application of soft X-ray spectroscopy to the study of valence band electronic states in metals and alloys. Therefore, the spectral region of 25 to 800 angstroms involving ruled glass grating spectrometers is of principal interest. In addition to soft X-ray data, references on all pertinent aspects of the apparatus and experimental problems are included. Also listed separately are references of value in corroborating soft X-ray data with other results. Subject, author, X-ray band, material, and other indices are included.
