The coherence parameters of excited states formed in collisions of atoms with electrons, positrons, protons and antiprotons are calculated using the Classical Trajectory Monte Carlo (CTMC) method and the results are compared to those obtained from the quantal distorted wave and close-coupling calculations. The orientation parameter and the components of the electric dipole moment of the electronic charge cloud after the collision are examined for excitation and for electron capture toH(n = 2) states. It is found that the CTMC results are in qualitative agreement with the quantal distorted wave and close-coupling results for some of the coherent parameters only.
