The optical potential is calculated from elastic scattering angular distribution data at high energies. The potential derived from elastic scattering data does not satisfactorily describe the experimental result for low energy reactions. An alternative approach for improving the α-optical potential at low energy was proposed, based on the (α,n) reaction, which is solely dependent on the α- transmission coefficient, i.e. on the alpha optical potential. The new potential is a modified McFadden-Satchler (McF) potential with depth parameters (both real and imaginary) changed by an energy dependent Fermi function. The sensitivity of (α,n) cross-section with different width parameters is also studied.
