Abstract
Fine structure in the ground-state proton radioactive decay of highly deformed has been identified. In addition to the previously observed ground-state line, measured here with a proton energy of 932(7) keV, a second proton peak with energy 811(7) keV was observed. We interpret this line as proton decay from the ground state to the first excited state of the daughter nucleus . Comparing the measured branching ratio with calculations enables the ground-state configuration of to be unambiguously assigned to the [411] Nilsson configuration.
