摘要：

The cause for backbending in 180-182Os and 181Re nuclei is studied using a theoretical description which includes the possibility of Coriolis antipairing (CAP), rotational alignment (RAL) and deformation jumps (DEJ). It is found that the h 9 2 protons play no important role as advocated by Neskakis et al. Practically the total angular momentum of the system is instead found to be due to the RAL of i 13 2 neutron pairs. To produce the backbending one needs a sudden enough RAL of i 13 2 neutron pairs, and this RAL seems to depend on the details of the single particle levels which in turn are influenced strongly by the hexadecapole deformation. Indications are found that the γ-DEJ may also be responsible for backbending in this mass region. © 1978.
