Background: At energies above the capture barrier, coupled-channels (CC) calculations with a standard nuclear potential diffuseness (0.65 fm) increasingly overestimate experimental capture cross section as the charge product ($Z_1{Z}_2$) of the colliding nuclei increases. It has been suggested this may be linked to energy dissipation outside the capture barrier.

重离子反应中的能量耗散和捕获截面的抑制

背景：在捕获壁垒以上的能量下，具有标准核势扩散（0.65 fm）的耦合通道（CC）计算越来越高估了作为电荷乘积的实验捕获截面（${ž}_{\mathrm{1个}}{ž}_{\mathrm{2个}}$）碰撞核增加。已经提出，这可能与捕获壁垒外部的能量耗散有关。
