Configuration interaction wavefunction for positronium hydride.

A configuration interaction wavefunction is obtained for the pseudo-atom positronium hydride (consisting of one proton, one positron, and two electrons), using Slater orbitals centered on the proton as basis functions. A positive dissociation energy is calculated for the process PsH -~ Ps + tt. Comparison is made with previous calculations of this energy, and its actual value is predicted to be 0.009 au. The two-quantum annihilation rate also is calculated.
