Abstract
A theory is presented to calculate potentials for the elastic nuclear heavy-ion scattering in a phenomenological way. The density properties of finite nuclei are derived with a schematic ansatz for the interaction energy between nuclear matter. The same interaction energy is applied to the calculation of the real part of the heavy-ion potential, which is of the quasimolecular type. The imaginary part is connected with the outflow time of nuclear matter out of compressed regions of overlapping nuclei. The resulting cross section for the elastic O16-O16 scattering reproduces the experiment up to 30 MeV quite well. An effective compression modulus of the S32 compound system can be deduced from the scattering experiment. It results to be about 200 MeV.
