Experimental study of theNe20+C12system

Excitation functions for elastic, inelastic, and four-particle transfer channels of the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ + ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ system were measured from 17 to 35 MeV (c.m.). The elastic scattering data (excitation functions and angular distribution at 24.7 MeV) have been analyzed with the optical model. Elastic and inelastic scattering are also studied in the framework of the coupled-channel Born approximation. The results emphasize the importance of the $2^{+}$ state of ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ in the description of the absorption. The comparison with the ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ + ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ system is discussed.
