Main Article Content
Abstract
In this research, the stopping power of charged particles was calculated using the Bethe, Bragg and Ziegler equations for protons and the alpha particle in polymethylmethacrylate C5O2H8 and polyacrylic acid C3O2H4 in the MeV energy range (0.01-1000). The Bethe, Bragg and Ziegler equations were used and the equations were programmed using MATLAB 2021. The calculations were compared with the imperical data of the P-STAR, SRIM 2013 and A-STAR programs. This comparison showed good compatibility with the imperical data in the medium and high energy region for the Bethe equation. The results also showed that the stopping power calculated according to the Ziegler equations corresponds well with imperical data in all energy ranges. The correlation coefficient was (0.9). These targets were chosen for their importance in the industrial and chemical fields.
