Abstract

Six new rotational bands have been established in I115 at high spin using the near symmetric Ni60(58Ni,3p) reaction at 250 MeV. Several of the bands are observed to frequencies beyond Latin small letter h with stroke=1.0 MeV (spin approaching 50Latin small letter h with stroke). 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.
