A classical and semiclassical study of collisions between Xq+ ions and water molecules

Collisions of He2+, Li3+ and C3+ ions with water molecules are studied at energies ranging between 20 keV u-1 and 500 keV u-1. Three methods are employed: the classical trajectory Monte Carlo (CTMC), the expansion of the scattering wave function in terms of asymptotic frozen molecular orbitals (AFMO...

Sumario:Collisions of He2+, Li3+ and C3+ ions with water molecules are studied at energies ranging between 20 keV u-1 and 500 keV u-1. Three methods are employed: the classical trajectory Monte Carlo (CTMC), the expansion of the scattering wave function in terms of asymptotic frozen molecular orbitals (AFMO) and a lattice method to numerically solve the time-dependent Schrödinger equation (GridTDSE). Total cross sections for single ionization, single electron capture, transfer ionization and electron production are calculated and compared with previous close-coupling calculations and experiments. The fragmentation branching ratios are discussed
