The microscopic alpha-alpha potential

The alpha-alpha potential is derived from the Skyrme effective nucleon-nucleon interaction using the folding model and the energy-density model with density-dependent terms and also the resonating group model. The unphysical Pauli states occurring in some of these potentials were removed using the Marchenko inversion method and the supersymmetric transformation. This gives an alpha-alpha potential that is both microscopically based and consistent with the experimental data. The off-shell characteristics of this potential are studied and their importance for various reactions discussed.
