Fusion Enhancement for Neutron-Rich Light Nuclei
Abstract
Measurement of the fusion cross-section for neutron-rich light nuclei is crucial in ascertaining if fusion of these nuclei occurs in the outer crust of a neutron star. The fusion excitation function at near-barrier energies for the O + C system was measured and the experimental results are compared to the fusion excitation function of O + C and O + C. The experiment was performed by utilizing a beam of O, produced via the O(d,p) reaction, to bombard a C target at energies near the Coulomb barrier. Evaporation residues produced in fusion of O ions with C target nuclei were detected with good geometric efficiency and identified by measuring their energy and time-of-flight. A significant enhancement is observed in the fusion probability of O ions with a C target as compared to O ions. The larger cross-sections observed at near barrier energies is related to significant narrowing of the fusion barrier indicating a larger tunneling probability for the fusion process.
