摘　　要：本文描述了一个用于计算快离子在无定形结构靶材料中引起的损伤能量分布的计算程序HEDEP-1。程序中采用了I.Manning等发展的近似计算方法,在处理入射离子与靶原子碰撞过程中考虑了核力影响,在电子阻止本领计算中选用了最新发表的J.F.Ziegler等数据。程序适用的能量范围是较宽的,从L.S.S.能区一直延伸到弹-核系统的库仑势垒以上,可以计算单质和多至四种元素组成的均匀靶材料。A computer program HEDEP-1, written by FORTRAN 77 and run on microcomputer, was developed in order to calculate the depth distribution for swift ion-radiated damage ene- rgy in the amorphous materials. The approximation method developed by I. Manning et al. was used in the program. The effects of nuclear force as treating incident ions collision with target atoms were considered. The data of electronic stopping powers given by J. F. Ziegler were used. HEDEP-1 can accept complex targets made up of component materials with ele- ments up to four different kinds and all ions inperiodic table of the elements with energy up to 100 MeV/amu.
