Excitation functions for 5 exit channels of the 12C + 20Ne system are given in the range 22-28 MeV centre of mass incident energy. An important structure is observed in the elastic scattering excitation functions taken at 90° and 130° (C.M.). This structure, which reminds one of the 16O + 16O case, is studied in terms of angular momentum matching. An angular distribution taken at 24.7 MeV (C.M.) is also presented. The direct channel absorption is shown to be intermediate between the 16O + 16O and 18O + 18O cases.
