Calculating the stopping power of protons and alpha particles in polycarbonate (PC)  and polyurethane (PU)

In this study, the alpha particle in polycarbonate and protons were studied by using the Bethe, Bragg, and Ziegler equations to determine the stopping power of charged particles. and polyurethane over the energy spectrum from 0.01 to 1000 MeV. The Bethe equation was found to be well-compatible with the experimental data in the medium and high energy area when the calculations were compared with the data from P-STAR, SRIM 2013, and A-STAR. The equations were coded in MATLAB 2021. The findings also shown that, across all energy ranges, the stopping power computed using the Ziegler equations agrees well with experimental data. There was a 0.9 correlation coefficient. The significance of these targets in the chemical and industrial domains led to their selection.
