| 摘 要： | By using Bonderup and Hvelplund's formulation the energy straggling for light ions (such as H~+, He~(+2)) etc) in each element has been calculated based on the IPM potential. The results obtained in this paper not only reveal a Z_2 oscillation and energy dependence) but also give a single parameter IPM electron density function n(r) which is fitted by Hartree-Fock (HF) model. Merover, we suggest a very simple theory method for calculating energy straggling of a compound of a mixing matter with mean atomic number Z_2~* and adjustable parameter d~* except additivity rule, the results are in good agreement with recent experiments.
