abstract
The reaction 31P(t, p)33P has been used to identify the ground state and 18 excited states 33P. The L-values of the neutron pairs transferred to seven of the levels were determined and spectroscopic arguments used to suggest spins and parities. Shell-model calculations have been carried out using five sets of two-body interaction matrix elements, and the results were compared to the observed relative peak cross sections. The same calculations were also used in a discussion of the reaction 34S(d, 3He)33P and the + decay of 33Ar to T = 3 2 levels in 33Cl. The sensitivity of the two-nucleon transfer reaction to small differences in the calculated wave functions is emphasized. 1969.
