Structure of the 90,94Zr nuclei: Global analysis of data on the elastic and inelastic scattering of alpha particles and on the total cross sections for the reactions induced by their interaction with these nuclei

Abstract

A global analysis of experimental data on the elastic and inelastic scattering of alpha particles by 90,94Zr nuclei and on the total cross sections for their interaction with these nuclei is performed. The deformation lengths and the neutron-to-proton multipole-matrix-element ratios for the 21+ and 31− states of the 90,92,94,96Zr nuclei are obtained for various projectile species, and a comparative analysis of these quantities is performed. With the aim of revealing the origin of the phase shifts found in the present study, experimental data on the inelastic scattering of 35.4-, 40.0-, 50.1-, and 65.0-MeV alpha particles on 90,94Zr nuclei are analyzed on the basis of a unified approach.
