An investigation of the (p,d) reaction on N=Z nuclei in the 2s-ld shell has been made to obtain spectroscopic information and to study the l n = 2 /-dependence for the (p,d) reaction. The experiments were performed with 24 Mg, 28 Si, 32 S, 36 Ar, and 40 Ca as target nuclei, and virtually all of the 2s-ld shell hole strength was observed. Deuteron angular distributions for strongly excited levels in 23 Mg, 27 Si, 31 S, 36 Ar, and 39 Ca were measured for laboratory angles from 10° to 155°, and spectroscopic factors were obtained using distorted-wave Born-approximation (DWBA) calculations. The / dependence for the pickup of an l" = 2 neutron appears mostly in the forward angles of the angular distributions and seems to follow systematic trends through the 2s-ld shell, thus suggesting spin assignments for levels in 31 S, 38 Ar, and 39 Ca. Appreciable configuration mixing is found to exist in the ground-state wave functions of all the nuclei investigated. Of particular interest are the l n = 1 levels excited in the ^Mg^^J^Mg and 28 Si (p,d) 27 Si reactions, which could arise from the removal of either Ip-or 2j?>-shell neutrons. The ground states of 36 Ar and 40 Ca are observed to contain appreciable mixing with the fy% shell, and evidence exists for a small [2p2 2 admixture in the 40 Ca ground state. The level orders of the residual nuclei and the DWBA spectroscopic factors are discussed in terms of the strong-coupling rotational model and Nilsson-model wave functions. Evidence for strong rotational band mixing is apparent in many cases. (p,d)REACTION ON N = Z NUCLEI
