Quantification of 242Pu with a Microcalorimeter Gamma Spectrometer
David J. Mercer, Ryan Winkler, Katrina E. Koehler +18
We report measurements of the 103-keV and 159-keV gamma ray signatures of 242Pu using microcalorimetry. This is the first observation of these gamma rays in a non-destructive measu…
Gamma and Decay Energy Spectroscopy Measurements of Trinitite
D. J. Mercer, K. E. Koehler, M. P. Croce +5
We report gamma ray spectroscopy measurements of trinitite samples and analogous samples obtained from detonation sites in Nevada and Semipalatinsk, as well as in situ measurements…
Improved Plutonium and Americium Photon Branching Ratios from Microcalorimeter Gamma Spectroscopy
Michael D. Yoho, Katrina E. Koehler, Daniel T. Becker +15
Photon branching ratios are critical input data for activities such as nuclear materials protection and accounting because they allow material compositions to be extracted from mea…
Production of A=6,7 Nuclides in the Alpha + Alpha Reaction and Cosmic Ray Nucleosynthesis
David J. Mercer, Sam M. Austin, J. A. Brown +6
Cross sections for production of 6He, 6Li, 7Li, and 7Be in the alpha+alpha reaction were measured at bombarding energies of 159.3, 279.6, and 619.8 MeV, and are found to decrease r…
