Abstract

The (p, t) and (p, 3He) reactions on 35, 37Cl are used to study the mirror and analogue states in Cl and S isotopes. The T = 32 states are identified at 5.55, 6.95, 7.35 and 8.10 MeV in 33Cl and at 5.65 and 7.25 MeV in 35Cl. Angular distributions for the strong transitions are obtained and analysed using a zero-range DWBA theory. The ratio of (p, t) and (p, 3He) cross sections are within theoretical limits. Shell-model calculations in the model space (2 s12, 1 d32)n have been carried out with four sets of two-body interaction matrix elements and the resulting level schemes and relative peak cross sections for (p, t) and (p, 3He) reactions are compared with experiment. Possible deficiencies in the model are discussed.
