Investigation of exotic structure in 34 Na by complex momentum representation combined with Green’s function method

Abstract

The study of exotic nuclei is one of the most interesting topics in nuclear physics. 34Na has attracted additional attentions for an odd-odd nucleus with special structure. Here, we combine the complex momentum representation (CMR) and Green's function (GF) to establish the CMR-GF method for the exploration of exotic structure, such as halo, skin, the level inversion and so on, in 34Na. The available density distributions, the configuration occupations, and the root mean square radius for the orbit occupied by the last valence neutron suggest a pwave single-neutron halo or skin structure in 34Na.
