The authors study the full density matrices (differential as well as integrated with respect to impact parameter) for charge transfer and excitation to the n=2 and 3 manifolds of the excited hydrogen atoms formed in p-H collisions over impact energies 1-50 keV. The scattering amplitudes are determined using the modified two-centre atomic-orbital-expansion method (AO+) based on the impact parameter formalism. From these scattering amplitudes several physical parameters such as the dipole moment, velocity vector, charge density and current distribution are extracted. The analysis of these parameters allows the authors to provide an approximate classical orbital picture for excitation and charge transfer to each manifold at both the low (E 20 keV) energy regions.
