The 6,7Li(p, d) Reaction at 185 MeV

Deuteron spectra have been measured for (p,d) reactions in 6Li and 7Li for angles between 2.5° and 30° (lab). In the studied separation energy range, ES < 40 MeV, two groups of peaks appeared, separated by 15 to 20 MeV. They were associated with 1p and 1s pickup, respectively. Spectroscopic factors were extracted from a DWBA analysis and were found to be compatible with the expectations of the shell model. The position of a broad peak in the 1s region of the spectra varies with the momentum transfer so as to indicate quasi-free pickup from an α-particle in the target nucleus.
