A SIMPLE EFFECTIVE INTERACTION FOR PERIPHERAL HEAVY-ION COLLISIONS ATINTERMEDIATE ENERGIES

A very simple phenomenological nucleon-nucleon effective interaction i s derived by folding-model analyses of 36 sets of heavy-ion elastic-sc attering data at energies E/A between 10 and 100 MeV. It is represente d by a single Yukawa term with a complex strength that varies slowly w ith energy. It is appropriate for peripheral collisions at intermediat e energies. It is proposed for use in consistent analyses of elastic- and inelastic-scattering measurements. The possible role of spin-orbit coupling in heavy-ion elastic scattering at the higher energies is di scussed.
