“…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.

“…Earlier publications on proton scattering from the zinc isotopes include papers by Jabbour et a1 [1,2] at an energy close to ours (22 MeV), but using an unpolarized beam. Tait et a1 [3,4] used a polarized beam at a somewhat higher energy (30.5 MeV). In their work the ground state and the 2: and 3; levels were studied for ".66s68Zn and no polarization data were reported for "Zn.…”

“…In this paper we wish to communicate some results on the scattering of '20. 4 MeV polarized protons hom the even-mass zinc isotopes 6(66,68370Zn. While this work was in progress, the Stichting voor Fundamenteel Onderzoek der Materie (FOM) announced its decision to end the support that our group had received for many years, because of the necessity to reduce its budget.…”

Measurements are reporled on polarized-proton scattering from the even-mass zinc isotopes at 20.4MeV beam energy. The elastic and first-order inelastic processes are represented well by standard theory. The analysis of the two-phonon multiplets presents difficulties which may indicate a change in the nuclear structure between isotopes or the occurrence of an energy-dependent interfering process.NUCLEAR REACTIONS 64,66.68,mZn (polarized p,p') E = 20.4MeV; measured o(e), A(0); deduced optical model parameters, deformation strengths for 2 : and 3; states.
