主　　题：Classical trajectory Monte Carlo Heavy ion-water molecule collision Inelastic cross sections 

摘      要：Inelastic collisions are the dominant cause of energy loss 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 *** 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/*** total cross sections,single differential cross sections,impact parameter dependence of SI and SC,and fragmentation cross sections were *** illustrate that the cross section for SI is the highest when the projectile energy is close to the Bragg peak *** the projectile energy is below the Bragg peak energy,the ionized electrons in the forward direction dominate,and the removal of electrons can be associated with large impact *** the projectile energy increases,the emission angle of the electrons gradually transitions from small angles(60°~120°)to large angles(60°~120°),and the removal of electrons is associated with small impact *** energy distributions of the ionized electron are similar when the projectile energy is equal to,below or above the Bragg peak *** fragmentation cross sections after SI and SC in the energy range around the Bragg peak were also estimated.
