Title: Nucleon correlations and the structure of Zn 41 30 71

Abstract

Here, the structure of 71Zn was investigated by one-neutron transfer and heavy-ion induced complex (deep-inelastic) reactions using the GRETINA-CHICO2 and the Gammasphere setups, respectively. The observed inversion between the 9/2 + and 1/2 states is explained in terms of the role of neutron pairing correlations. Non-collective sequences of levels were delineated above the 9/2 + isomeric state. These are interpreted as being associated with a modest oblate deformation in the framework of Monte-Carlo shell-model calculations carried out with the A3DA-m Hamiltonian in the pfg 9/2d 5/2 valence space. Similarities with the structure of 68 28Ni 40 were observed and the shape-coexistence mechanism in the N = 40 region of neutron-rich nuclei is discussed in terms of the so-called Type-II shell evolution, with an emphasis on proton–neutron correlations between valence nucleons, especially those involving the shape-driving g 9/2 neutron orbital.
