The "P( He, d) "S reaction was investigated at 25 MeV incident energy. One-hundred and eleven levels up to an excitation energy of 12.5 MeV were observed using a split-pole magnetic spectrograph. The experimental angular distributions were analyzed with the distorted-wave Born approximation. The optical model parameters used in the distorted-wave Born-approximation calculations were obtained from a fit to elastic He scattering data taken on "P at 25 MeV. Gamow functions were used as form factors for the transferred proton in the case of unbound states. Values of the transferred orbital angular momenta l and spectroscopic strengths were obtained for sixty levels, with many odd-parity levels being observed above 9 MeV excitation. Spin and parity assignments were made upon the basis of the l values obtained from the shapes of the angular distributions and upon comparison with the results of other reactions. Isospin assignments were made by comparison with P levels. Except for the l~= 1, T = 0 transfers, most of the observed spectroscopic strength is concentrated into a few levels. The existence of a T-mixed doublet of levels, J"= 1, is suggested in the 11 MeV region of excitation. The excitation energies and spectroscopic strengths are compared with results of a recent shell-model calculation.

The ' 6Ge(d, He) 9 ' Ga reactions have been studied at 26 MeV with 15-keV resolution full width at half maximum using a tandem accelerator and split pole magnetic spectrometer. The spectroscopic factors are determined for 15 levels in Ga and 11 levels in each of the 3 other Ga isotopes. Level schemes are proposed for the practically unknown 3Ga and 'Ga. Anomalies in the occupation numbers are observed between Z = 31 and 32 and between N = 40 and 42, this last one corresponding to the structural transition observed recently in acomparison of the (p, t) and (t, p) reactions. These anomalies could be related to changes in the nuclear shape. NUCLEAR REACTIONS 7 ' '74' Ge(d, 3He), E=26 MeV; measured 0.
