A simple double-folding computation of the complex heavy-ion optical potential

We have derived a spin- and isospin-independent complex effective force to compute the 16O + 16O optical potential by the double-folding procedure. To avoid reference to a wave function, we have used superposition models to compute the values of the matter and intrinsic kinetic energy densities necessary to the local specification of the effective force. The present results compare favourably with those of a previously published, fully antisymmetrized calculation. The physical significance and the quantitative importance of self-energy effects are discussed. (orig.)
