Abstract
A -ray spectroscopy study of resonant states in is presented. Excitation energies were measured with improved precision and first spin-parity assignments made for excited states in above the proton threshold. The results indicate the presence of low-lying resonances with and captures that could strongly influence the reaction rate at low stellar temperatures, found in low-mass asymptotic giant branch (AGB), intermediate-mass AGB, super AGB, and Wolf-Rayet stars.
