Fusion and nonfusion phenomena in the 6Li + 40Ca reaction at 156 MeV

Abstract Reaction products from 6 Li-induced reactions on 40 Ca at 156 MeV have been studied using the d E × E identification as well as the inclusive γ-ray method. The complete fusion cross section has been found to be σ F = 67 ± 20 mb. The Z -distribution of fusion evaporation residues is compared with statistical model predictions. The Z -spectrum of reaction products shows a maximum at 15 ≲ Z ≲ 20, probably due to transfer and to incomplete fusion. It is suggested that the small value of the fusion cross section is due to the strong competition of 6 Li break-up processes.
