Title: Coulomb Breakup and Reaction Cross Sections for Deformed Halo Nucleus ^31Ne
Abstract:
A halo structure with an extended density distribution is one of the
characteristic features of weakly bound neutron-rich nuclei. For the neutron-rich nucleus ^31Ne, the halo structure has been recently suggested by the experimental data of Coulomb breakup and interaction cross sections measured at RIKEN RIBF facility.
Assuming that ^31Ne consists of the strongly deformed core nucleus ^30Ne and one valence neutron, we calculate Coulomb breakup and reaction cross sections of ^31Ne taking into account the rotational excitation energy of the core nucleus ^30Ne with particle-rotor model (PRM). We will discuss the structure of ^31Ne deduced from these calculations.
