Calculation of Stopping Power for Protons, Carbon and Oxygen Ions in C2H4O, C3H3N Polymers

In this research , the electronic stopping power was calculated using Bethe and Bragg rule equations for the protons , carbon and oxygen ions in the polymers (C 3 H 3 N ,C 2 H 4 O) in energy range of (0.01-1000) MeV. The equations were programmed using MATLAB 2016 , the calculations were compared with the experimental data of the SRIM2013program and PSTAR code. This comparison showed a good agreement with experimental data . As shown results that stopping power calculated according to Bethe equation in this polymers (C 3 H 3 N ,C 2 H 4 O) get the case a cut off in energies (0.01-8) MeV for carbon and oxygen ions
