Study of the low-lying structure of the N=49 nucleus, $^{81}$Ge

ORAL

Abstract

The properties of low-lying levels of nuclei near N=50 are important for understanding the evolution of nuclear shell structure further from stability and the rapid neutron capture process, which may occur in supernovae. The low-lying levels of the N=49 nucleus $^{81}$Ge have been studied by measuring the $^{80}$Ge(d,p)$^{81}$Ge reaction at 310 MeV (3.875 MeV/u) in inverse kinematics at the Holifield Radioactive Ion Beam Facility in Oak Ridge National Laboratory. The primary goal of this work is to determine the spins of $^{81}$Ge levels using the angular distribution of observed protons. Details of the experimental setup and a status report on the data analysis will be discussed.
