Differential cross sections for the elastic and inelastic scattering of neutrons from the s-d shell nuclei /sup 28/Si, /sup 32/S, /sup 34/S and /sup 40/Ca have been measured in the 19-26 MeV region. For /sup 28/Si and /sup 32/S the measurements were done at 21.7 MeV. For /sup 34/S the neutron measurements were done at 21.7 and 25.5 MeV. Also data for the elastic and inelastic scattering of protons from /sup 34/S were measured at 29.8 MeV. For /sup 40/Ca the neutron measurements were done at 19.0, 21.7 and 25.5 MeV. The present data for /sup 28/Si and /sup 32/S were analyzed in terms of rotation-vibration and anharmonic vibration collective models respectively. Isoscalar E2, E3, and E4 transition matrix elements were obtained from the normalized multipole moments of the real potential and the results were compared with those obtained from electromagnetic probes and from nuclear structure theoretical calculations.
