ملخص: An indirect transmission method as nuclear technique in precise measurement of energy loss straggling in polymer foils is presented. The details of experimental procedures related to the combination of Rutherford backscattering spectrometry and transmission technique are described. Advantages of the application of such a method in energy straggling experiments are discussed. The energy loss straggling measurements have been performed in the energy range of 900-3000 keV for protons and deuterons in thin films of polypropylene. The obtained values of energy straggling are compared to those deduced from Bohr and Bethe-Livingston theoretical predictions. This comparison was made by using Bragg’s rule as model of calculation over the investigated energy range.
