Energy and expectation values of the PsH system

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 PsH${}^{\infty }$ energy was -0.789196740 hartree which is the lowest variational energy to date. The 2$\gamma$ annihilation rate for PsH${}^{\infty }$ was $2.47178\times 10^9$ s${}^{-1}$.
