“…Our knowledge on the structure of 65 Ni comes mainly from (n,γ) experiments performed about 40 years ago [13][14][15][16], deep-inelastic scattering experiments from the 90's [17], (d,p) reaction studies [18][19][20] and β-decay studies [21]. The aim of this work is to perform a complete low-spin spectroscopic study of 65 Ni, by using a (n,γ) reaction, in order to significantly expand our understanding of its low-spin structure and search for signature of shape coexistence.…”

An extended investigation of the low-spin structure of the 65 Ni nucleus was performed at the Institut Laue-Langevin, Grenoble, via the neutron capture reaction 64 Ni(n,γ) 65 Ni, using the FIPPS HPGe array. The level scheme of 65 Ni was significantly expanded, with 2 new levels and 87 newly found transitions. Angular correlation analyses were also performed, allowing us to assign spins and parities for a number of states, and to determine multipolarity mixing ratios for selected γ transitions. The low-energy part of the experimental level scheme (up to about 1.4 MeV) was compared with Monte Carlo Shell Model calculations, which predict spherical shapes for all states, apart from the 9/2 + and the second excited 1/2 − states of oblate deformation.
