Sub-threshold excited Cl K. beta. (K-V) x-ray fluorescence from CF/sub 3/Cl molecule

Description: With the availability of tunable synchrotron radiation sources, unoccupied molecular orbits (below vacuum level) can be selectively populated producing highly excited neutral molecules. X-ray fluorescence spectra from molecules were obtained with excitation below the ionization threshold and were observed to have significant intensity changes, absolute and relative energy position shifts and line width changes as compared to fluorescence spectra excited above the threshold. As an example, the C… more

High resolution krypton M/sub 4,5/ x-ray emission spectra

Description: High resolution M/sub 4,5/ (3d ..-->.. 4p) x-ray emission spectra from a krypton plasma were measured using a recently developed grazing-incidence reflection-grating monochromator/spectrometer with very high flux rates at extreme ultraviolet and soft x-ray wave lengths. The nominal resolving power of the instrument, E/..delta..E, is about 300 in this energy range (approx.80 eV). Three dipole-allowed 3d ..-->.. 4p emission lines were observed at 80.98 eV, 80.35 eV and 79.73 eV. A broad peak at a… more

Durability of various cements in a well of the Cerro Prieto geothermal field

Description: The durability of each of 16 different cements was evaluated by both room temperature compressive strength and water permeability measurements, following various periods of treatment of the cements in flowing geothermal fluid of the Cerro Prieto field of Mexico. Some of these cements were selected through a Department of Energy program to develop improved cements for geothermal well completion while the others were contributed by several other institutions interested in the tests. Two types of … more

A Survey of the Literature on Heat Transfer From Solid Surfaces to Cryogenic Fluids

Description: A bibliography of 156 references on heat transfer from solid surfaces to fluids and related phenomena is presented. Heat transfer data obtained from experimental work on cryogenic fluids are presented in graphical form. The theoretical and empirical formulations appearing in the references are presented. In those cases where sufficient information is available to make numerical computations, the formulations are presented graphically to permit comparison with the results of the experimental wor… more

What About Metric?

Description: Pamphlet issued by the United States National Bureau of Standards discussing the reasons that the U.S. decided passed the Metric Conversion Act of 1975 and provides tables, illustrations, and formulas for converting between customary units and metric units of measuring weight, length, volume, and temperature. It also includes a discussion of how one might expect to use metric measurements in the marketplace, in the home, and at work.

Spectrometric Techniques for Measuring Environmental Gamma Radiation

Description: From Introduction: "We discuss in detail the equipment, calibration procedures, and techniques used to analyze the spectra, present evidence to substantiate the validity of the dose rate estimates, and examine several problems associated with field measurements, in particular the effects of radon migration from the soil, soil moisture, and fallout."

Evaluation and compilation of DOE waste package test data: Biannual report, August 1986-January 1987

Description: This report summarizes results of the National Bureau of Standards (NBS) evaluations of Department of Energy (DOE) activities on waste packages designed for containment of radioactive high-level nuclear waste (HLW). The waste package is a proposed engineered barrier that is part of a permanent repository for HLW. Metal alloys are the principal barriers within the engineered system. Technical discussions are given for the corrosion of metals proposed for the canister, particularly carbon and sta… more
