An excitation function for the {sup 12}C({sup 20}Ne,{sup 12}C[0{sub 2}{sup +}]){sup 20}Ne reaction was measured over the energy range E{sub c.m.}=22.5{endash}31.9 MeV. An enhancement in the cross section was observed between E{sub c.m.}=24.5 and 26.5 MeV in both the {sup 12}C(0{sub 2}{sup +})+{sup 20}Ne(g.s.) and {sup 12}C(0{sub 2}{sup +})+{sup 20}Ne(2{sup +}) exit channels. Oscillatory angular distributions were observed at E{sub c.m.}=25.24, 26.56, 28.50, and 30.44 MeV and the range of dominant angular momenta involved at these energies was found to be centered on 14{h_bar},15{h_bar},16{h_bar}, and 17{h_bar}, respectively. Excitation functions were also measured for the {sup 12}C({sup 20}Ne,{sup 12}C[3{sup {minus}}]){sup 20}Ne{sup {asterisk}} reaction. For the {sup 12}C({sup 20}Ne,{sup 12}C[0{sub 2}{sup +}]){sup 20}Ne reaction the data were well described by the results of coupled channel calculations. {copyright} {ital 1999} {ital The American Physical Society}
