Stopping Power and Range Calculation of Electrons in NH3, PH3, AsH3, SbH3 Molecules

The research included a theoretical study in calculating the electronic stopping power of light particles (electrons) with an energy range of (0.01 -100) MeV for NH₃, PH₃, AsH₃ and SbH₃ molecules. The equations were programmed in mathematical ways and implemented in a mathematical program written in MATLAB2021 to obtain the required theoretical results, illustrated in graphs. The theoretical results obtained from this study were compared with the experimental results of the E-STAR program for electrons. The results showed a good agreement by calculating the correlation coefficient (r) of not less than 0.9. The range of electrons in molecules has also been calculated in the same energy range, In general, our calculations showed a good agreement with the other data, which we compared with it.
