Inelastic differential cross sections of 22 MeV proton scattering for
5 excited states of Si-28 have been measured from 10-degrees to 115-de
grees. Empirical effective interactions were extracted within the fram
e of DWBA from the normal parity state data which transition densities
were known from electron scattering. The fitting is good except for t
he forward angle of 4(1)+ and 0(2)+ states. The results are discussed.
