Close to converged energies and expectation values for e+ PsH are computed using a ground-state wave function consisting of 1500 explicitly correlated Gaussians. The best estimate of the e+ PsH ground state can be regarded as consisting of a weakly bound positron orbiting the PsH ground state. � 2007 The American Physical Society.
