Abstract
The level structure of and in the high excitation energy/high spin regime was studied using -ray spectroscopy and Doppler shift lifetime measurements following and reactions. Multiple new levels and transitions were identified in both nuclides based on coincidence data. In , evidence was found for higher-spin negative-parity states up to resulting from neutron excitation into the shell, in good agreement with shell model calculations using the SDPF-MU and FSU interactions. Candidates for the yrast and levels in , consistent with calculations using the USDB interaction, were also identified.
