Abstract:

The α-α transition operator-effective interaction, tαα(E, \vecr) has been evaluated using phenomenological α-α optical potentials at several bombarding energies, Eα from 77 to 200 MeV. The results are obtained by solving the Schrödinger equation with appropriate optical potentials for various partial waves and then clubbing these with their respective optical potentials and initial state plane waves. The change of the α-α optical potential with or without hard core has been shown to influence the effective α-α t-matrix interactions drastically. The behaviour of the calculated tαα(E,\vecr) effective interaction indicates towards a solution of the large anomalies found in the (α,2α) reaction analyses.
