The internucleus potentials of the ${}_{}{}^{16}{}_{}{}^{}\mathrm{-}_{}^{16}{}_{}{}^{}$O, ${}_{}{}^{12}{}_{}{}^{}\mathrm{-}_{}^{16}{}_{}{}^{}$O, ${}_{}{}^{12}{}_{}{}^{}\mathrm{-}_{}^{12}{}_{}{}^{}$C, and α${\mathrm{-}}^{16}$O systems are calculated by using the Skyrme-type forces in the framework of the canonical moving wave packet method. The volume integrals $j_v$ 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 ‖$j_v$‖ 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.
