Neutron transition densities from [sup 88]Sr([ital p],[ital p][prime]) at [ital E][sub [ital p]]=200 MeV

1993 
New cross section and analyzing power data for [sup 88]Sr([ital p],[ital p][prime]) at [ital E][sub [ital p]]=200 MeV are reported and analyzed together with earlier cross section data. Neutron transition densities for low-lying normal-parity excitations were extracted using an empirical density-dependent effective interaction and an expansion of the radial density which permits analysis of uncertainties due to penetrability, distortion, incompleteness, statistics, and normalization. The densities were compared with shell-model calculations using effective operators based upon a density-dependent Hartree-Fock approximation. Good agreement between theory and experiment is obtained for the 2[sub 1][sup +], 3[sub 1][sup [minus]], and 5[sub 1][sup [minus]] states, but the experimental neutron densities for the 2[sub 2][sup +] and 7[sub 1][sup [minus]] states are considerably stronger than expected. Both proton and neutron transition densities for the 2[sub 2][sup +] state have strong interior lobes, but the theory fails to reproduce the accompanying surface lobes.
