Angular distributions for the elastic and inelastic alpha scattering from {sup 28}Si at {ital E}{sub {alpha}}=40 and 45 MeV are analyzed in the framework of microscopic folding model. Transition densities are calculated from improved {ital s}-{ital d} shell-model wave functions and are also compared with those extracted from inelastic electron scattering data. The density-dependent Jeukenne-Lejeune-Mahaux interaction is used, besides the M3Y interaction, in an attempt to fit the large-angle data. Fairly good agreement with the data is obtained. The extracted {ital M}{sub {ital n}}/{ital M}{sub {ital p}} value for the 2{sup +} excited state of {sup 28}Si also compares well with the shell-model prediction.
