Abstract

We perform the first quantitative analysis of the reaction cross sections of 2832^{28-32}Ne by 12^{12}C at 240 MeV/nucleon, using the double-folding model (DFM) with the Melbourne gg-matrix and the deformed projectile density calculated by the antisymmetrized molecular dynamics (AMD). To describe the tail of the last neutron of 31^{31}Ne, we adopt the resonating group method (RGM) combined with AMD. The theoretical prediction excellently reproduce the measured cross sections of 2832^{28-32}Ne with no adjustable parameters. The ground state properties of 31^{31}Ne, i.e., strong deformation and a halo structure with spin-parity 3/23/2_{}^-, are clarified.
