Investigation of the elastic and inelastic scattering of He-3 from Be-9 in the energy range 30-60 MeV

摘要

We have measured the differential cross-sections for the elastic as well as inelastic scattering populating the 2.43 MeV (5/2(-)) excited state in Be-9 using He-3 beams at energies of 30, 40 and 47 MeV on a Be-9 target. The experimental results for the elastic scattering were analyzed within the framework of the optical model using the Woods-Saxon and double-folding potentials. The theoretical calculations for the concerned excited states were performed using the coupled-channel method. The optimal deformation parameters for the excited states of Be-9 nucleus were extracted.
