The 118Sn(7Li, 6He)119Sb reaction at 48 MeV

Angular distributions have been measured for transitions to low-lying states in 119Sb populated in the 118Sn(7Li, 6He)119Sb reaction at E7Li = 48 MeV. Elastic scattering of 7Li at 48 MeV and 6Li at 42 MeV was measured and optical model parameters determined by fits to the angular distributions. The optical model parameters deduced were used in a finite-range DWBA analysis of the transitions to states at 0.0, 0.27, 0.66 and 1.35 MeV excitation energy in 119Sb. Generally the data exhibited less structure than was predicted by the DWBA calculations, but the extracted spectroscopic factors are generally in good agreement with other results. The same types of discrepancies between calculations and data observed with heavier projectiles, are also observed for 7Li induced reactions.
