A Precision Angular Correlation Table and Calculation of Geometrical Correction Factors (open access)

A Precision Angular Correlation Table and Calculation of Geometrical Correction Factors

In recent years y-y angular correlations have been very useful in confirming the spins of excited nuclear states. Angular correlation techniques have also been employed to study the electric and magnetic character of excited nuclear states. With these things in mind, it was decided to design, construct, and test a precision angular correlation table.

Nuclear Reactions on the Palladium Isotopes (open access)

Nuclear Reactions on the Palladium Isotopes

The problem of interest in this investigation was to determine the cross sections of five nuclear reactions which occur when irradiating natural palladium with neutrons which have energy values of 15.1, 15.9, and 16.3 MeV. The cross sections were measured relative to a copper monitor which was "sandwitched" in with the palladium target.

A Study of the Decay Levels of 169/Tm69 (open access)

A Study of the Decay Levels of 169/Tm69

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 (open access)

Carbon Contamination Measurements in Single Silicon Crystals

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.
