摘要
利用额外推力模型研究了4 8Ca + 2 38U俘获和熔合过程中的靶核形变效应 .计算表明 ,在近垒和垒下能区 ,靶核形变使俘获截面和熔合截面增强 ,形成的复合核自旋分布展宽 .
Effects of target deformation on the capture and fusion processes of the 48 Ca+ 238 U system are investigated in the framework of extra push model.The reults of our investigation indicate that target deformation enhances the capture and fusion cross sections for heavy system forming superheavy nuclei,and broadens the spin distribution of the corresponding compound nuclei at near and sub barrier energies.
