The rotational alignment of hei/2 neutrons is considerably delayed (Aha-0. 11 MeV) in the nbii/z[550] -, ' intruder band in " I 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 hii/2 neutrons and the hi]12 proton intruder may also play a role. In addition, noncollectible oblate states at
