Inelastic collisions are the dominant cause of energy loss in radiotherapy. In the energy range around the Bragg peak, single ionization (SI) and single-electron capture (SC) are the primary inelastic collisions that lead to energy loss. This study employs the classical trajectory Monte Carlo method to study the SI and SC processes of H $$_{2}$$ O molecules using He $$^{2+}$$ and C $$^{6+}$$ projectiles in the energy range of 10 keV/u to 10 MeV/u. The total cross sections, single differential cross sections, impact parameter dependence of SI and SC, and fragmentat...
