Influence of the shell structure of the target nucleus on. cap alpha. emission in (nucleon,. cap alpha. ) reactions
Journal Article

· Phys. Rev. C; (United States)
The unusual energy distribution of ..cap alpha.. particles emitted in the reaction /sup 143/Nd(n,..cap alpha..)/sup 140/Ce at incident energies 12--18 MeV, is explained as being due to the shell structure of /sup 143/Nd in the hypothesis that the mechanism responsible for ..cap alpha.. emission is the knockon by the incident neutron of ..cap alpha.. particles performed in the target nucleus. The same interpretation is offered to describe the spectrum of ..cap alpha.. particles in the reaction /sup 209/Bi(p,..cap alpha..)/sup 206/Pb.
