In this work, we expand upon our previous study, the effect of hot nuclear matter on the calculation of the internuclear potential [Phys. Rev. C 84, 024612 (2011)], to the 28Si + 40Ca, 35Cl + 48Ti, and 40Ar + 74Ge collision systems. For this purpose, we have employed the equation of state of hot nuclear matter, which is based on density-dependent Seyler-Blanchard formalism at finite temperature, to discuss the energy dependence of a repulsive core potential in the nucleon-nucleon interaction. The obtained values for strength of this potential show a linear dependence as a function of excitation energy E ∗ (or temperature T ) of the compound nucleus. Indeed, it is predictable that the effect of hot nuclear matter on heavy-ion reactions can be formulated by an additional energy-dependent function in the nucleon-nucleon potential.
