Monte Carlo Calculations of Reflected Intensities for Real Spherical Atmospheres

Monte Carlo Calculations of Reflected Intensities for Real Spherical Atmospheres

Date: January 1969
Creator: Montgomery, John A.
Description: To calculate the emergent radiation field, a realistic atmospheric model and algorithm must be developed. The radiation field may be characterized by the emergent intensities of scattered light. This is possible only if the algorithm determines these intensities as dependent upon atmospheric and angular parameters.

Size Effect in the Electrical Conductivity of Bismuth

Size Effect in the Electrical Conductivity of Bismuth

Date: August 1967
Creator: Vaughn, Bobby J.
Description: If a physical dimension of a metallic specimen is comparable with, or smaller than, the mean free path of the conduction electrons, then the observed electrical conductivity will be less than that of a conventional bulk sample. This phenomenon is called a size effect, and is the result of electron scattering from the specimen surfaces. In the present investigation, measurements were made on electropolished monocrystalline specimens ranging from matchbox geometry to thick-film geometry in order to obtain further information on the size effect in bismuth at liquid helium temperatures.

A Determination of the Bothe Depression Factor for Discs in Water

A Determination of the Bothe Depression Factor for Discs in Water

Date: August 1950
Creator: Patton, Bob
Description: The purpose of this work is to determine experimentally the depression of the neutron density by a detecting foil. The depression factor is known as the "self-shading" of the foil.

A Study of the Decay Levels of 169/Tm69

A Study of the Decay Levels of 169/Tm69

Date: December 1970
Creator: Harris, Robert J.
Description: The purpose of this investigation was to study the radiations of the 169/Tm nucleus as it de-excites after the electron capture decay of the 169/Yb. Numerous unreported gammas were present in the sample. The origins of these gamma rays were found.

Carbon Contamination Measurements in Single Silicon Crystals

Carbon Contamination Measurements in Single Silicon Crystals

Date: December 1970
Creator: Logsdon, Lawrence E.
Description: The intent of this investigation was to directly measure the amount of carbon contamination in a single silicon crystal and, in so doing, develop a mathematical procedure that would be applicable to other contaminants in other substances.
