Hindrance of heavy-ion fusion at extreme sub-barrier energies in open-shell colliding systems
Hindrance of heavy-ion fusion at extreme sub-barrier energies in open-shell colliding systems
The excitation function for the fusion-evaporation reaction 64Ni+100Mo has been measured down to a cross-section of ~5 nb. Extensive coupled-channels calculations have been performed, which cannot reproduce the steep fall-off of the excitation function at extreme sub-barrier energies. Thus, this system exhibits a hindrance for fusion, a phenomenon that has …
