摘要：

Six new rotational bands have been established in 115I at high spin using the near symmetric Ni-60(Ni-58,3pgamma) reaction at 250 MeV. Several of the bands are observed to frequencies beyond HBARomega = 1.0 MeV (spin approaching 50HBAR). All the bands show a characteristic drop off in their dynamic moments of inertia with increasing spin. The low values at the highest spins are consistent with predictions for a band termination in which a gradual shape change from collective prolate to noncollective oblate occurs over many transitions. These smoothly occurring terminations contrast with the abrupt ''favored'' terminations previously observed in this and other odd-A iodine nuclei.
