The Si/sup 28/(d,p gamma )Si/sup 29/ reaction was studied by measuring angular distributions of the protons leaving Si/sup 29/ in its first and second excited states and by measuring the correlation between the protons of each group and the gamma rays emitted from the corresponding level. The angular distributions of proton groups p/sub 1/ and p/sub 2/ exhibit large peaks in the backward direction, indicating that heavy-particle stripping may be important. The (p/sub 1/, gamma ) correlations were found to be isotropic to plus or minus 6%. This is substantially different from the correlation which was observed at a higher deuteron energy. The (p/sub 2/, gamma ) cor relations are consistent wlth a 5/2+ level in Si/sup 29/ at 2.03 Mev. One (p, gamma ) correlation shows a 20% anisotropy in the plane perpendicular to the direction taken by the recoil nucleus, while another (p, gamma ) correlation is essentially isotropic. (auth)
