Abstract
Neutron elastic and inelastic scattering differential cross sections from zirconium isotopes, 90,91,92,94Zr have been mesured at neutron incident energies E n = 8.0, 10.0 and 24.0 MeV. The obtained neutron energy resolutions were 135, 188 and 410 keV (FWHM) for neutron scattering at 8.0, 10.0 and 24.0 MeV, respectively. The elastic scattering data are used to study the isospin dependence of the empirical OMP. The inelastic data are compared with results of DWBA calculations to obtain deformation length values, δ L , for low-lying collective states. The ratio of neutron and proton transition matrix element, M n / M p , are deduced for those low-lying collective states in 90,92,94Zr using the present neutron data and published results of proton data DWBA analyses. An excited-core model analysis of inelastic neutron scattering data from 91Zr is presented.
