(6Li, 6He) at intermediate energies

Angular distributions have been measured for the (6Li, 6He) reaction on targets of 7Li, 12,14C, 26Mg and 90Zr at bombarding energies of 35, 25 and 14 MeV/A. The ratios of observed cross sections for states in 14N and 7Be suggest that the reaction mechanism is predominantly one-step at 35 MeV/A with an increasing contribution from sequential transfer at lower energies. One-step DWBA calculations at 35 and 25 MeV/A are consistent with the data. Good proportionality is observed between the measured cross sections for Gamow-Teller transitions and the corresponding β-decay matrix elements
