Reactions induced by 18MeV 6He beam on 6Li, 7Li and 12C

The He-6+Li-6,Li-7 and He-6+C-12 scattering and reactions have been studied using a 18 MeV He-6 beam. Experimental results for the elastic scattering on all three targets are in fair agreement with optical model predictions, using the potentials found in the analysis of the Li-6 scattering on the same targets and at close energies. Large cross sections are observed for a-transfer reactions to some states of Be-10. The sequential decay reactions He-6+Li-6-->He-6+alpha+d, He-6+Li-6-->2alpha+t+n, He-6+Li-7-->He-6+alpha+t and He-6+C-12-->Be-10+2alpha, were clearly seen and analysing them alpha-clustering of some states in Li-6, Li-7, Be-8, Be-9, Be-10 and C-14 was recognized.
