用1800个显式关联的高斯态组成的基态波函数计算了PSH的近收敛能量和期望值。对${mathm{ps}}^{susuremathm{infty}}mathm{H}$能量的最佳估计是$ensureath{-}0.789幻象{

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 ${mathrm{Ps}}^{ensuremath{infty}}mathrm{H}$ energy was $ensuremath{-}0.789phantom{

ule{0.2em}{0ex}}740phantom{
ule{0.3em}{0ex}} ext{hartree}$ which is the lowest variational energy to date. The $2ensuremath{gamma}$ annihilation rate for ${mathrm{Ps}}^{ensuremath{infty}}mathrm{H}$ was $2.471phantom{
