Clustering phenomena in the (α,⁷Li) reaction at E _α=27.2MeV=27.2MeV

The B-11, N-15 and F-19(alpha, Li-7) reaactions have been studied at E(alpha) = = 27.2 MeV to investigate the cluster structure of the above target-nuclei. The measured Li-7(g.s) and Li-7(0.478) angular distributions are analyzed with the contributions coming from the statistical and direct processes. The spectroscopic factors of the studied cluster configuration for the target-nuclei were deduced. The results are compared with the ones deduced by other authors at various incident energies.
