摘要：
Relativistic effects in the ground-state energy of positronium hydride up to orders O(alpha(4)mc(2)) and O ((mu/M) alpha(4)mc(2)) are calculated using fully correlated basis sets in Hylleraas coordinates. The resulting binding energy against the dissociation into a positronium and a hydrogen is 1.06 041 68(27) eV. The two-photon annihilation rate is also calculated and the result is 2.472 208(20) nsec(-1).
