The authors have determined full density matrices of excited He{sup +} (2 and 3) and Na (3p and 3d) atoms produced in He{sup 2+} - Na(3s) collisions at 2-50 keV/amu. A two-center coupled-Sturmian-pseudostate approach is employed to determine the corresponding amplitudes for the electron transfer and target excitation channels. Various cross sections for charge transfer and target excitation compare very well with experimental data. From the on- and off-diagonal density matrix elements, several physical parameters, corresponding to s-p and p coherences, have been determined and compared with available experimental data and recent theoretical calculations. In particular, the authors have studied the behavior of dipole moment, velocity vector, orientation, and alignment quantities with respect to the projectile velocity and impact parameter.
