Abstract

Excitation spectra and neutron single particle configurations of ³³Mg and ³¹Ne are investigated by using antisymmetrized molecular dynamics combined with generator coordinate method. It is shown that both nuclei have strongly deformed 3/2^- ground state with a 3p2h configuration. The excitation spectra are qualitatively understood in terms of the Nilsson model and the calculation has shown the coexistence of different intruder configurations within small excitation energy. The calculated one neutron separation energy of ³¹Ne is rather small (S_n=250 keV) and implies a p-wave one neutron halo with a strongly deformed core.
