Inelastic Triton Scattering fromZr92,94,96

Abstract

The inelastic scattering of 20-MeV tritons from ${}_{}{}^{92}{}_{}{}^{}\mathrm{Zr}$, ${}_{}{}^{94}{}_{}{}^{}\mathrm{Zr}$, and ${}_{}{}^{96}{}_{}{}^{}\mathrm{Zr}$ has been studied. The principal objective was to obtain an effective interaction strength to be used in a microscopic description of the excitation of neutron states. Only the lower levels of ${}_{}{}^{92}{}_{}{}^{}\mathrm{Zr}$ and ${}_{}{}^{94}{}_{}{}^{}\mathrm{Zr}$ were studied, but because of the paucity of available data on ${}_{}{}^{96}{}_{}{}^{}\mathrm{Zr}$, this isotope is studied in a more complete way, with 28 levels and 17 spins assigned. The shell-model results indicate a much smaller effective interaction strength for the excitation of neutron states than noted earlier for proton states in triton inelastic scattering.
