Abstract
Close to converged energies and expectation values for PsH are computed using a ground state wave function consisting of 1800 explicitly correlated gaussians. The best estimate of the Ps H energy was -0.789 196 740 hartree which is the lowest variational energy to date. The 2? annihilation rate for Ps H was 2.471 78�109 s-1. � 2006 The American Physical Society.
