Theory of complete and incomplete fusion of weakly bound systems

Theory of complete and incomplete fusion of weakly bound systems

We propose a new method to evaluate complete and incomplete fusion in collisions of weakly bound nuclei. The method is applied to the Li7+209Bi system and the results are compared to experimental data. The overall agreement between theory and experiment is extremely good, above and below the Coulomb...
