Abstract
Excited states in the Z = 85 nucleus At-197 have been identified for the fi rst time using the recoil-decay-tagging (RDT) technique. The excitation ene rgy of these states is found to be consistent with the systematics of neutr on-deficient astatine nuclei and with theoretical calculations indicating t hat the nucleus may be deformed in its ground state.
