2023AM04 Phys.Rev. C 108, 014612 (2023) Dynamical mechanism of fusion hindrance in heavy ion collisions NUCLEAR REACTIONS ^{208}Pb(^{48}Ca, X), E(cm)=180 MeV; calculated fusion probabilities in collision process, one-dimensional fusion barrier dependence on initial angular momentum, mass distribution of fission fragments, trajectory distribution and time evolution.
