Abstract
In this work, we study the mechanism of the nuclear reaction of 11B ion with 181Ta and 209Bi targets at intermediate energies and analyze the nuclear reaction processes starting from the initial nucleus-nucleus collision up to the fragments production. The experimental data are derived from the literature Karapetyan et al. (Phys Rev C 94: 024618, 2016). A new branch of CRISP model has been extended in the framework of the rotating liquid drop model to describe heavy-ion-induced reactions. Experimental mass-yield distribution is compared with the results of the Monte Carlo simulation code CRISP using the theoretical model calculations. The experimental data of spallation products are also described by the CRISP model. The fission cross sections, fissility and fragment mass distributions are calculated and compared with experimental data. We conclude that CRISP model provides a good description for the cases analyzed in this study and gives us confidence that it might be applied to other cases as well. (AU)
