摘要

本文用IPM离子–原子作用系统势，直接计算了轻离子（如

He）在部分气体、固体中的能量歧离值Г

（

）

肯定了Г

（

）随元素的原子序数

和离子能量

的变化关系。在入射质子能量

=340keV和992keV时，与近期的Y. Kido实验值，Lindhard-Scharff和W. K. Chu的理论值作了对比，发现本文的计算结果与实验值在2.5—4%偏差内相符合，优于其它理论方法。

Abstract

The energy stragglings of light ions such as

H and

He in partial gases and solids are calculated by IPM potential directly

and the

value varies with the atomic number of target atom

and the incident ion energy

. The present results calculated are in good agreement with the recent experiments by Y. Kido within 2.5—4.0%.
