Angular correlation measurements from the β decay of ¹⁶⁶mHo and ¹⁶⁶Tm and the properties of the gamma vibrational band in ¹⁶⁶Er

Creator:

Loats, Jeffrey T.

Abstract:

Angular correlations of gamma rays from excited states of ¹⁶⁶Er have been measured following the β decays of ¹⁶⁶ Ho (Jπ =7-, t 1/2 =1200y, Q= 1854 ke V) and ¹⁶⁶Tm (Jπ = 2+, t 1/2, = 7.7h, Q=3040 keV). Data was collected using the 8π spectrometer, an array of...

Angular correlations of gamma rays in the decay of ¹⁰⁹Pd and ¹¹¹Pd

Creator:

Brown, Daniel E.

Abstract:

Measurements have been made of γ -γ directional correlations on the following cascades, following the decay of ¹¹¹Pd and ¹⁰⁹Pd : In ¹¹¹Ag : (454, 633, 762 - 391) keV (526, 797 -633) keV (526, 797 -[633] -391) keV In ¹⁰⁹Ag : (390, 413, 424, 551, 558 - 311) keV...

Special Nuclear Material Analysis Using Temporal Gamma-Ray Spectroscopy and Machine Learning Methods

Creator:

Curtis, Jessica R.

Abstract:

Following thermal neutron induced fission, supervised machine learning and temporal gamma-ray spectroscopy methods were used to identify differences in the delayed gamma-ray spectra of Pu-239 and U-235. The temporal gamma-ray spectroscopy method takes advantage of the time-dependent decay of fission products. Employing Spearman's rank-order correlation coefficient and without prior knowledge...
