The dinuclear system (DNS) model has been widely used to explain different heavy-ion reactions such as fusion, quasifission and fission. In previous studies, the DNS is treated as a local N / Z equilibrium system formed after the capture process in the final stage of the reaction. In this work, we generalize the DNS concept to describe the multi-nucleon transfer (MNT) reaction in the dynamical radial process. By treating the ensemble of projectile and target at any distance as the dinuclear system, we solve the semi-classical dynamical radial equation and the master equation for the proton and neutron distributions in the dinuclear system (DyDNS) simultaneously for the first time. In this method, the classical radial movement is coupled to the internal quantum single particle transition between the colliding nuclei. The dynamical Monte Carlo method is engaged to simulate the solutions, and then the GEMINI++ model is adopted to deal with the de-excitations. To illustr...

从动力学双核系统方法的角度看多核子转移反应

双核系统（DNS）模型已被广泛用于解释不同的重离子反应，例如聚变，准裂变和裂变。在以前的研究中，DNS被视为反应的最后阶段在捕获过程之后形成的局部N / Z平衡系统。在这项工作中，我们概括了DNS概念，以描述动态径向过程中的多核子转移（MNT）反应。通过将任意距离的弹丸和目标的集合视为双核系统，我们首次同时求解了双核系统（DyDNS）中质子和中子分布的半经典动力径向方程和主方程。在这种方法中，经典的径向运动耦合到碰撞原子核之间的内部量子单粒子跃迁。运用动力学蒙特卡洛方法对解进行仿真，然后采用GEMINI ++++模型进行去激励处理。为了说明...
