ملخص: Experimental studies of slowing down of 1H, 2H and 4He in Makrofol KG nuclear track material in the ion energy range 1.0:3.6 MeV are presented. The ion stopping powers obtained are compared with the predictions of two widely used semi:empirical models: the cores and bonds (CAB) model and Bragg’s rule, predicted by TRIM 92 computer code. The CAB model is found to overestimate the observed stopping powers and the deviation observed is about 10%. Choice of the transmission technique and foil thickness determination method are investigated.
