Description
Semiclassical model GRAZING is able to predict well the experimental data of many medium heavy multinucleon transfer (MNT) reaction systems. However, only simple neutron evaporation in the deexcitation of primary fragments is considered in the model. Evaporation and fission of the primary fragments generated by multinucleon transfer reaction are simultaneously included using GRAZING model, accompanied with Monte Carlo statistical model GEMINI++ and GEMINI for the first time. Different experimental isotope cross sections of MNT reaction systems are adopted to testify the theoretical models. It’s found that by combining GRAZING model with GEMINI++ model, theoretical predictions of final isotope cross sections can be improved by taking into account charged particle evaporation, especially the evaporation of alpha particles. Due to the considering of fission in the deexcitation of primary fragments by GEMINI++ model, distributions of final fragments are much wider than original approach. GEMINI model highly overpredicts the fission probability and width of fission isotope distributions compared with results of GEMINI++ model.
