Abstract 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(infinity) energy was -0.810 254 hartrees, which has a binding energy of 0.021 057 hartrees against dissociation into e(+)+PsH. The 2 gamma annihilation rate was 2.7508x10(9) s(-1). Binding energies and annihilation rates are also given for the different finite-mass variants of e(+)PsH. Comparisons between expectation values for e(+)PsH and PsH provide compelling evidence that the e(+)PsH ground state can be regarded as consisting of a weakly bound positron orbiting the PsH ground state.
