Transition densities in 30Si studied by electron scattering and coupled-channel calculations of 650 MeV proton scattering.

R. Alarcon Nuclear Physics Laboratory and Department ofPhysics, University ofIllinois, Champaign, Illinois 61820 (Received 8 October 1987) Proton and neutron transition densities in ' Si are examined by a combination of intermediate energy (e,e') and (p,p') reactions and mirror electromagnetic transition rates. This analysis is performed for the 2+i and 22 states at 2.234 and 3.499 MeV in Si. Electron scattering data are presented for these states. Shell-model calculations for the proton and neutron transition matrix elements and proton transition densities are compared with the electromagnetic results. The proton transition densities are reasonably predicted for the 2+l state but are not adequately predicted for the
