Nucleon interaction with Ni-58 up to 150 MeV studied in the coupled-channels approach based on the soft-rotator nuclear structure model - art. no. 044605

The soft-rotator model was applied to understand the collective nuclear str ucture, electromagnetic transition, and the nucleon (both neutron and proto n) interaction data of Ni-58 in a consistent manner. It was found that the model could describe the collective level structure of Ni-58, which does no t,exhibit the typical rotational or harmonic vibrational structure, up to e xcitation energy of 4.5 MeV modestly. The nucleon interaction data were des cribed up to 150 MeV reasonably well by the coupled-channels method with a coupling scheme constructed consistent to the nuclear structure of Ni-58.
