Abstract: Angular distributions of the elastic α + 12C scattering in range of incident energies from 65 to 240 MeV were described well in optical model with folded potentials calculated from effective nucleon-nuclen interaction. The density-dependent interaction CDM3Y6 was used to generate the optical potentials. Enhancements of cross section at large angle in 104 and 110 MeV data were assumed to be due to contributions of the 8Be transfer process. We had perfromed copuled reaction channel (CRC) analyses to estimate the 8Be transfer affects on the elastic α + 12C scattering. Our analysis results had shown that the contrinbutions of both one-step and two-step 8Be transfer process are important and necessary.
