Abstract: (APS)

Differential cross sections for inelastic proton scattering at 800 MeV have been measured for a number of low-lying states in Zr90, Sn120, Sm144, and Pb208. The data from this and earlier experiments on Ca40 and Ni58 were analyzed with a collective vibrational model to obtain separate neutron and proton deformation lengths, making use of electromagnetic measurements. Ratios of neutron to proton transition matrix elements are calculated. These ratios are generally less than NZ for the open proton shell nuclei and greater for the open neutron shell nuclei. NUCLEAR REACTIONS Zr90, Sn120, Sm144, Pb208(p,p′), E=800 MeV; measured σ(θ), θlab=5°−20°. Optical model and DWBA collective model analysis. Deformation lengths and neutron to proton matrix element ratios are extracted for the above and Ca40, Ni58.
