“…For the the case of the Zn isotopes, the present measurements are below β 2 (EM). Previous measurements on stable Zn isotopes [66,70,72,74,75,[77][78][79][80][81][82][83] show similar values of β 2 (EM) and β 2 (p,p ) for 68,70 Zn and hint at a small increase on β 2 (p,p ) for 64,66 Zn.…”

Proton inelastic scattering of 72,74 Ni and 76,80 Zn ions at energies around 235 MeV/nucleon was performed at the Radioactive Isotope Beam Factory and studied using γ-ray spectroscopy. Angular integrated cross sections for direct inelastic scattering to the 2 + 1 and 4 + 1 states were measured. The Jeukenne-Lejeune-Mahaux folding model, extended beyond 200 MeV, was used together with neutron and proton densities stemming from quasiparticle random-phase approximation (QRPA) calculations to interpret the experimental cross sections and to infer neutron to proton matrix element ratios. In addition, coupled-channels calculations with a phenomenological potential were used to determine deformation lengths. For the Ni isotopes, correlations favor neutron excitations, thus conserving the Z = 28 gap. A dominance of proton excitation, on the other hand, is observed in the Zn isotopes, pointing to the conservation of the N = 50 gap approaching 78 Ni. These results are in agreement with QRPA and large-scale shell-model calculations.
