Phys. Rev. C 58, 1966–1969 (1998)Neutron h11/2 band structures of 109,111Pd observed in heavy-ion induced fissionReceived 12 February 1998; published in the issue dated October 1998 The neutron-rich nuclei 109,111Pd have been produced as fission fragments following the fusion reactions 28,30Si+176Yb at 145 MeV and studied with the EUROGAM2 array. Two signature branches of a new band built on the νh11/2 orbital have been identified in 109Pd and the favored signature of the νh11/2 band has been observed for the first time in 111Pd. The spectroscopic properties as well as the rotational behavior of these bands are characteristic of bands expected for a prolate nuclear shape in this mass region. The effect of blocking of the first h11/2 quasineutron in the odd-A Pd nuclei supports the interpretation of the first crossing in the yrast bands of 110,112Pd as due to a ν(h11/2)2 pair. © 1998 The American Physical Society URL:
