REACTIONS 6LI(3HE,3HE0)6LI 6LI(D,D0)6LI 7LI(D,D0)7LI AND 6LI(3HE,D0,1)7BE

Angular distributions for 3He ions elastically scattered from 6Li were measured for nine bombarding energies between 8 and 20 MeV. The elastic scattering of deuterons by 6Li and 7Li was studied at 11.8 MeV. Optical model-parameters of the type V ≈ 50 MeV × A (projectile) and rw > rv were obtained, which are in fair agreement with parameter sets of the same type found for neighbouring nuclei. The parameters for the 3He elastic scattering show a smooth variation with incident energy in the range 8 to 20 MeV. Differential cross sections for 6Li(3He, d) to the 7Be ground state and the first excited state (0.43 MeV) were measured at 8, 10, 14 and 18 MeV. DWBA calculations using optical parameters derived from the elastic scattering 6Li+3He and 7Li+d yield only a qualitative description of the measured angular distributions. The ratio S*/S of the spectroscopic factors corresponding to 7Be(0.43) and 7Be(g.s.) is in fair agreement with the values derived from 6Li(d, n) and 6Li(d, p) reactions. © 1968.
