Fusion enhancement for neutron-rich isotopes of oxygen on carbon nuclei was probed. To measure the fusion cross-section a 20O beam accelerated to E_lab/A = 2.7 MeV bombarded the active-target detector MuSIC@Indiana with a fill gas of CH₄. Examination of the average fusion cross-section over the interval 0.5 ≤ (E c.m. –V_B)/V_B ≤ 1.2 for ^16–20O + ¹²C 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.
