600keV的荷能碳团族离子C+n（n=1─5）注入到NaCl单晶，当入射粒子的速度v大于玻尔速度v0（=c/137）时，能量转移主要是由入射粒子与靶原子的核外电子碰撞造成的。假定团簇中各原子的能量歧离大于它们的结合能时，团簇状态已经结束，各原子成为独立的粒子。利用Trim程序对碳团簇在NaCl单晶中的射程进行了模拟，得到团簇区域的长度为278－321nm，总射程为686nm。
When the incidental particle velocity v is greater than the Bohr velocity v0 (= c / 137), the energy transfer is mainly caused by the implanted particles of 600keV C + n (n = 1 ~ 5) With the target atom outside the nuclear collision caused. Assuming that the energy divergence of each atom in the cluster is greater than their binding energy, the cluster state is over and the atoms become independent particles. The range of carbon clusters in NaCl single crystal was simulated by Trim program, and the length of the cluster region was 278-321 nm with a total range of 686 nm.
