The reaction systems Ca48+U238 and Ca48+Cm248 are investigated within the improved dinuclear system model+GEMINI++. The theoretical results show that the distributions of isotopes in the Ca48+U238 reaction are well described with the model. For the Ca48+Cm248 reaction, the model partly describes well the experimental production cross sections. Experimental and theoretical data from multinucleon transfer reactions indicate that the isotopic distributions of the Ca48+U238 reaction system above Pb are shifted toward the neutron-rich side as compared to the Xe136+Pb208 reaction except the isotopic distribution of Bi.

反应系统 48+ü23848+厘米248在改进的双核系统模型+ GEMINI ++中进行了研究。理论结果表明,同位素在大气中的分布。48+ü238该模型很好地描述了反应。为了48+厘米248反应,该模型部分很好地描述了实验产品的横截面。来自多核子转移反应的实验和理论数据表明48+ü238 与Pb相比,Pb上方的反应系统向富中子侧移动 e136+铅含量208 除了Bi的同位素分布以外,其他反应都没有。
