Abstract: | Distributions of cross sections and analysing powers have been measured over the range ~ 14°–100° c.m. for the reactions at 33.4 MeV incident e using a ~ 95 % enriched 30Si target. Phenomenological optical-model analyses of the elastic-scattering data have been carried out. A DWBA analysis of the inelastic-scattering data for the 2.24 MeV (2+) and 5.49 MeV (3?) states of 30Si has yielded values of the deformation β2 and β3. The j-dependence of the analysing powers for the (3He, 4He) and (3He, 2H) reactions has identified the 6.71 MeV level of 29Si as a state, and a level near 9.5 MeV in 31P as a possible state. Spectroscopic factors for ten states in 29Si and seven states in 31P have been deduced and are compared with other work. The extent to which the data defines the 3He spin-orbit potential is discussed. |
