Alpha elastically scattered by light nuclei 6,7Li, 9Be, and 11 B, has been analyzed in the framework of Coupled Reaction Channel (CRC) and Crystal Model (CM) folded with Distorted Wave Born Approximation (CM+DWBA) approach. Also, 6Li elastically scattered by 12C at wide range of energies has been studied with CRC and CM+DWBA. The effect of transfer on the elastic scattering has been studied to extract the spectroscopic amplitudes for 6Li≡α+d, 7Li≡α+t, 9Be≡α+5He, 11B≡α+7Li and 12C≡6Li+6Li configurations from backward angles of the experimental data under consideration. Crystal Model has been applied for deuteron elastically scattered by 6Li and 7Li where CM+DWBA+DPP succeeded to reproduce the differential cross sections for the whole range of angles. The obtained analyses from CRC for alpha elastically scattered by light nuclei 6,7Li, 9Be, and 11 B were better than those from CM which produces the need for developing the CM in the near future. Fair agreement has been observed between applied models and the considered experimental data.
