Abstract
The rotational alignment of h11/2 neutrons is considerably delayed (DELTA-HBAR-omega approximately 0.11 MeV) in the pi-h11/2[550]1/2- intruder band in I-117 when compared to bands built on normal-parity states. Comparison with cranked shell-model calculations suggests that this effect may indicate a larger quadrupole deformation for the intruder orbital. A strong neutron-proton interaction between the aligning h11/2 neutrons and the h11/2 proton intruder may also play a role. In addition, noncollective oblate states at I(pi) = 39/2-, 43/2-, and 45/2(-) compete energetically with rotational states of the intruder band which may also perturb the neutron alignment.
