Abstract

Excitation functions for the yields of eight residual nuclides from the ¹⁶O + ²⁰Ne reaction have been measured over the range E_c.m.=15-29 MeV using γ-ray techniques. Weak oscillatory structure in the fusion-evaporation yield is observed, with maxima near E_c.m.=20, 22, and 23 MeV. Two strong anomalies in the inelastic scattering and α-transfer channels have been located at E_c.m.=19.9 and 25.4 MeV. These structures have properties similar to those of characteristic resonances in other light systems. The E_c.m.=19.9 MeV resonance occurs at the same ³⁶Ar excitation energy as a similar resonance previously observed in the ¹²C + ²⁴Mg reaction yields.
