英文摘要: Much interest has recently been devoted to the shape evolution of neutron-rich Si isotopes both experimentally and theoretically. We present our study of Si28-42 using the Skyrme-Hartree-Fock model with the Bardeen-Cooper-Schrieffer approximation for the pairing channel. We use an empirical pairing parameter deduced from the experimental binding energy data for each nucleus and each Skyrme parametrization. The recent highlight of the deformation change from the prolate shape of Si-38 to the oblate shape of Si-42 is confirmed in the present model. We also emphasize the role of the tensor force in deformations of neutron-rich Si-30,Si-32, and discuss its underlying physics.
