Elucidation of complex decay schemes using on-line mass separated sources and a large array of Compton-suppressed germanium detectors

ORAL

Abstract

Complex decay scheme construction using beta decay of isotopes produced by spallation and mass separation on-line at TRIUMF-ISAC and studied with the 8$\pi$ array of 20 Compton-suppressed germanium detectors is described. Results from the analysis of the $^{160}$Yb $\rightarrow$ $^{160}$Tm decay will be presented. Emphasis will be placed on the sensitivity to weak decay branches, assignment of $\gamma$-ray lines to isobars, and the use of conversion electron coincidences to observe low-energy transitions. The goal of this work is to achieve detailed decay scheme spectroscopy far from stability with the same level of detail as obtained with the 8$\pi$ array near stabilty in earlier $N=90$ studies [1] [2]. \newline [1] W.D.
