We study the formation of cusps in the double differential cross section for ion-atom ionization collisions by means of a classical trajectory Monte Carlo calculation. The use of an `importance sampling' algorithm allows us to improve the efficiency

We employ a three-body classical trajectory Monte Carlo (CTMC) method to calculate the recoil-ion momentum distribution at its kinematic threshold in ion-atom ionization collisions. We analyse how this threshold is intertwined by dynamical constraint

The differential cross sections for electron transfer in -Na(3s) collisions in the 0.4-14 keV energy range are studied using the impact parameter semiclassical method and a 28-state molecular orbital basis model including a common translational facto

The orientation and alignment effects for charge exchange in H+ + Na*(3p) collisions are studied using the classical trajectory Monte-Carlo method in the energy range from 1 to 8 keV. For Na*(3p -1) → H*(2s, 2p ±1) transitions a large orientation

The electron capture process from Na*(3p+or-1)) atoms by a proton has been studied both classically and semiclassically in the energy range from 1 to 10 keV. In the classical model, we have developed a three-body classical trajectory Monte Carlo (CTM
