Abstract

Elastic and inelastic scattering of α-particles by 9Be nuclei have been analyzed with different incident energies. Optical model parameters (OMPs) of elastic scattering of α-particles by 9Be were obtained on different energies. The Elastic scattering, inelastic scattering and transfer reaction using Coupled Reaction Channel (CRC) method were obtained using Fresco Code. The effect of involving CRC calculations on the differential cross section analysis has been examined. The transfer reaction of (5He) was studied in reaction 9Be(α,9Be)α. spectroscopic factor of 9Be as α+5He configuration was derived from experimental data. Also investigated is the effect of coupling to the excited states 1/2+ and 5/2- of 9Be, and its effect on elastic scattering results. Static deformation has been extracted for 9Be nuclei.
The theoretical calculations have been done by codes have a good agreement with experimental data obtained from literature. One step of 5He transfer was sufficient to solve the oscillations in the middle angles of the differential cross section.
