Measurements of the potassium content of samples of food, performed with High Purity Germanium detectors, are presented in this paper. The potassium content was measured by identifying the 1460 keV photons produced in the decay of the isotope 40 K. Samples were selected, for which a high potassium content was expected. The measurements confirmed the expectations qualitatively, but not always quantitatively. Especially the expected dependence of the potassium content of chocolate on the listed percentage of cacao could not be confirmed.

“…Several programs were used initially to plot data "on the fly" because of their familiarity and therefore ease of use. These programs, HYPERMET [Ph76] and PKS [Wa88], are Windows-based programs which utilize a user-created input file and the data file to fit peaks specified by the user. A program called SIMPLEFIT was also used to integrate the area of the histograms given user-defined backgrounds and peak limits.…”

DISTRIBUTION/AVAILABILITY STATEMENTThis document has been approved for public release; its distribution is UNLIMITED. 12b. DISTRIBUTION CODE ABSTRACT:The purpose of nuclear structure research is to understand the features of the nuclear force that determine the various ways a nucleus can behave upon excitation. Theoretical model calculations are compared to experimental data in order to understand which models better predict different nuclear properties. The tellurium-130 nucleus has two valence protons with respect to a closed proton shell and several different types of nuclear structure behavior are thought to be active. Experimental data were collected at the University of Kentucky Nuclear Structure Laboratory using a technique called inelastic neutron scattering. By scattering neutrons off of 130 Te, the nucleus was excited, and the resulting de-excitation gamma rays recorded as 130 Te excited states relaxed. Through analytical techniques, the energy level scheme has been constructed, and spectroscopic information such as lifetimes, level spins, and branching ratios has been obtained.
