Description
A systematic investigation of fusion reactions induced by 16O is carried out. Within the double-folding formalism, the nu-
cleus–nucleus interaction potential is constructed using both density-independent nucleon–nucleon interactions (B3Y-Fetal, M3Y-
Paris, and M3Y-Reid) and density-dependent interactions (BDM3Y1, CDM3Y6, and DDM3Y1). The reactions 16O + 70,72,74,76Ge,
16O + 112,116,118,120Sn, 16O + 144,148,154Sm, 16O + 186W and 16O + 208Pb are considered. Two groups of interactions exhibiting similar
fusion cross sections are identified, with the similarities becoming more pronounced as the target mass increases. On one hand,
potentials derived from the B3Y-Fetal and BDM3Y1 interactions yield comparable fusion cross sections; on the other hand, those
obtained from the M3Y-Paris, M3Y-Reid, CDM3Y6, and DDM3Y1 interactions also produce similar results. The former group
generally provides a better description of the experimental data, except for the 120Sn for which the latter group offers the best fit.
The analysis of the channel couplings strength reveals that BDM3Y1 interaction corresponds to the strongest channel couplings. It
is also observed that the strength of channel couplings does not vary monotonically with the atomic mass, as might be expected.
In light of these results, it follows that the B3Y-Fetal and BDM3Y1 nucleon-nucleon interactions systematically provide a better
description of the experimental data. Furthermore, there are no specific features in the fusion cross sections that can be attributed
solely to whether the nucleon-nucleon interaction is density-dependent or density-independent. This conclusion is supported by the
identified two groups of nucleon-nucleon interactions, each containing density-dependent and density-independent interactions
