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.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
