Slow Collision

Differential and total cross sections for elastic scattering and resonant–near-resonant charge exchange have been computed for H+–H(1s) and H+–D(1s) collisions in the energy range 0 to ~0.1 eV, using a rigorous quantum mechanical formulation of slow collision theory in which all spurious couplings of the perturbed stationary states (PSS) theory are removed. Orbiting and shape resonances are described and compared in the two systems, and in addition the distinctive features of the HD+ case, such as the appearance of several Feshbach resonances in the region below the D+–H(1s) threshold, are identified and discussed. Most of the effects of the isotopic H(1s)–D(1s) splitting disappear at collision energies near the end of this range.

Molecule Scattering

The method of Hara using two centre formalism has been employed to investigate positron–hydrogen molecule scattering at low incident energies. Two model potentials have been used to see the importance of the choice of effective potential. It has been found that the total cross sections are sensitive to the details of the effective potential. The present results are in qualitative agreement with measured values and other existing theoretical predictions.
