j-Forbidden (d, p) Stripping Reactions on C12, O16 and Mg24

High resolution studies of the ( d , p ) reaction on C 12 at 14.6 MeV, O 16 at 14.3 MeV and Mg 24 at 12.3 MeV were performed. The C 12 ( d , p )C 13 reaction leading to the ground and the 3.68 MeV states was also investigated from 14.7 MeV down to 12.3 MeV. Some transitions which cannot be explained by simple stripping process were observed. Most of angular distributions of protons from the j -forbidden stripping reaction showed a structureless pattern and the cross section was 10∼30% of that of simple stripping process. Simple PWBA analyses based on the two step process and on the knock out process were made and a possibility of the two step process is suggested. The structure of some excited states is discussed in connection with the reaction mechanism.
