New model based on coupling the Master and Langevin equations in the study of multinucleon transfer reactions

Abstract

The multinucleon transfer process plays a crucial role for accessing unexplored isotopes far from the β-stable line. Developing reliable models is always one of biggest challenges for understanding the mechanism of the multinucleon transfer (MNT) process and providing accurate predictions. In this work, a new model, combining the Master and Langevin equations (CML), is developed for investigating the mechanism of the MNT reactions. The reaction 136Xe+208Pb is studied. The CML calculations are in rather good agreement with the experimental data. The effects of the incident energy and the entrance angular momentum on the production cross sections are investigated. One intriguing phenomenon is found that the dependence of the incident energy on the production yields in symmetry region is more intense than that for producing trans-target fragments.
