Determination of resonance energies and widths in Ps-H scattering using the stabilization method
Description
In an effort to explore computational methods to investigate resonances in atomic systems involving positrons, we present a calculation of resonances in positronium-hydrogen scattering, using the stabilization method. The density of resonance states is calculated using extensive Hylleraas-type wavefunctions. Resonance energies and widths for three S, two P, and two D states are determined, from the stabilization plots of the density of resonance states. Our results, obtained by using a real algorithm, are in good agreement with those obtained by using the method of complex-coordinate rotation
