Abstract
From an experiment with Gammasphere and a spontaneous fission source, a new negative-parity band in and new negative-parity levels in were identified and the yrast bands were extended to in and in in a triple gamma coincidence study. These new negative-parity bands are consistent with octupole vibrational mode. There is a constant difference as a function of spin between the values for the negative-parity band in and for the similar negative-parity band in however, their values are essentially identical. These bands indicate a new kind of identical band.
