Cross sections have been measured for 6Li(6Li,5He)7Be and for 19F(6Li,p)24Na in the laboratory energy range from 3.0 to 15.0 MeV. Similar measurements have been made for 6Li(d,n)7Be in the laboratory energy range from 0.4 to 1.0 Me V. A theoretical analysis of the 6Li(6Li,5He)7Be reaction, using a distorted-wave-Born-approximation calculation, shows that this and other experiments are consistent with a proton-transfer model in a direct-reaction mode.
