Population of low-spin levels in $^{75,77}$Ge in neutron-capture reactions

ORAL

Abstract

The structure of nuclei near $^{76}$Ge has been of interest owing to the possibility of neutrinoless double beta decay. To further characterize the low-energy, low-spin structure for $^{75}$Ge and $^{77}$Ge, we have studied the gamma rays following neutron capture on highly enriched $^{74}$Ge and $^{76}$Ge, respectively, in experiments performed at the cold-neutron beam line at the NIST Center for Neutron Research. The new spectra will be shown and insight into the level structures presented.
