Abstract

Fusion enhancement for neutron-rich isotopes of oxygen on carbon nuclei was probed. To measure the fusion cross-section a $^{20}$ O beam accelerated to E $_{lab}$ /A=2.7 MeV bombarded the active-target detector MuSIC@Indiana with a fill gas of CH $_4$ . Examination of the average fusion cross-section over the interval 12 MeV $\leq$ E $_{c.m.}$ $\leq$ 17 MeV for $^{16-20}$ O + $^{12}$ C reveals that while even isotopes of oxygen exhibit essentially the same cross-section, the cross-section for odd isotopes can be either enhanced or suppressed relative to the even A members of the isotopic chain. Theoretical models fail to explain the observed experimental results.
