Multinucleon transfer cross sections around targetlike fragments of the ${}^{58}\mathrm{Ni}+{}^{208}\mathrm{Pb}$ reaction and the ${}^{64}\mathrm{Ni}+{}^{207,208}\mathrm{Pb}$ reactions were calculated by the improved dinuclear system $\mathrm{model}+\mathrm{GEMINI}++$. One finds that the ${}^{64}\mathrm{Ni}+{}^{208}\mathrm{Pb}$ reaction is more favorable to obtain neutron-rich nuclei as compared to the ${}^{58}\mathrm{Ni}+{}^{208}\mathrm{Pb}$ and ${}^{64}\mathrm{Ni}+{}^{207}\mathrm{Pb}$ reactions. That is because the difference of injection point position on the potential energy surface has a significant influence on the transfer of protons and neutrons in multinucleon transfer reaction. The effect of the entrance channel on transfer cross sections was predicted and analyzed by ${}^{58,64,70}\mathrm{Ni}+{}^{198}\mathrm{Pt}$ and ${}^{86,91,102}\mathrm{Kr}+{}^{208}\mathrm{Pb}$ reactions.

入口通道对多核子转移截面的影响

靶样片段周围的多核子转移截面 ${}^{58}你+{}^{208}铅$ 反应和 ${}^{64}你+{}^{207,208}铅$ 反应由改进的双核系统计算 $\mathrm{模型}+\mathrm{双子座}++$. 有人发现，${}^{64}你+{}^{208}铅$ 与反应相比，反应更有利于获得富中子核 ${}^{58}你+{}^{208}铅$ 和 ${}^{64}你+{}^{207}铅$反应。这是因为势能面上注入点位置的差异对多核子转移反应中的质子和中子的转移有显着影响。入口通道对传输截面的影响预测和分析${}^{58,64,70}你+{}^{198}铂$ 和 ${}^{86,91,102}氪+{}^{208}铅$ 反应。
