Potential roots of the deep subbarrier heavy-ion fusion hindrance phenomenon within the sudden approximation approach
Potential roots of the deep subbarrier heavy-ion fusion hindrance phenomenon within the sudden approximation approach
We analyze the origin of the unexpected deep subbarrier heavy-ion fusion hindrance in $^{64}\mathrm{Ni}+^{100}\mathrm{Mo}$, $^{64}\mathrm{Ni}+^{64}\mathrm{Ni}$, and $^{28}\mathrm{Si}+^{64}\mathrm{Ni}$ reactions. Our analysis is based on the improved coupled-channels description, implemented by means of the finite element method. With the aid of the Woods-Saxon potential the experimental cross sections and the $S$ factors …
