Proton inelastic scattering of Ni-72,(74) and Zn-76,Zn-80 ions at energies around 235 MeV/nucleon was performed at the Radioactive Isotope Beam Factory and studied using gamma -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 Ni-78. These results are in agreement with QRPA and large-scale shell-model calculations.
