In this work, we study the mechanism of the nuclear reaction of \(^{11}\)B ion with \(^{181}\)Ta and \(^{209}\)Bi 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.

在这项工作中，我们研究了\（^ {11} \） B离子与\（^ {181} \） Ta和\（^ {209} \）的核反应机理。Bi的目标是中间能量，并分析了从最初的核－核碰撞到碎片产生的核反应过程。实验数据来自文献Karapetyan等。（Phys Rev C 94：024618，2016）。CRISP模型的新分支已在旋转液滴模型的框架中扩展，以描述重离子诱导的反应。使用理论模型计算，将实验的质量产率分布与蒙特卡罗模拟代码CRISP的结果进行比较。CRISP模型还描述了散裂产品的实验数据。计算裂变截面，裂变性和碎片质量分布，并将其与实验数据进行比较。
