Fusion and compound nuclei decay for light and intermediate-mass systems: ²⁴Mg, ²⁸Si + ¹²C ; ²⁴Mg + ^24,26Mg ; ²⁸Si + ²⁴Mg, ^28,29,30Si

Abstract

Complete fusion or residue distributions have been measured with several experimental techniques for the following systems: ²⁴Mg, ²⁸Si + ¹²C ; ²⁴Mg + ^24,26Mg ; ²⁸Si + ²⁴Mg, ^28,29,30Si. The range of energies spreads from 1 to 3 times the Coulomb barrier. None of these systems presents structures in its fusion excitation function as pronounced as the ones observed for lighter entrance channels. The intensities of the residue distribution are generally in agreement with the predicitons of the multiple deexcitation code CASCADE. The shape and absolute values of complete excitation functions are compared to macroscopic models and to the predicitons of a coupled-channel approach of the reaction, which gives a more satisfactory account of experimental data.
