STRENGTH OF THE ATTRACTION OF THE SKYRME-TYPE FORCES USED IN THE HEAVY-ION REACTION PROBLEMS

The internucleus potentials of the -1616O, -1612O, -1212C, and -16O systems are calculated by using the Skyrme-type forces in the framework of the canonical moving wave packet method. The volume integrals jv of the calculated potentials are compared with those of the real parts of the optical potentials which fit the data very well in a wide energy range. Compared with experiments, the calculated values of jv are found to have too weak energy dependence and to be too small in the incident energy region lower than about 40 MeV/nucleon. Finite-range nuclear forces are constructed with least modification to the Skyrme-type forces such that they reproduce the same nuclear matter properties as the Skyrme-type forces, and the properties of the internucleus potentials are studied by these finite-range forces. © 1990 The American Physical Society.
