摘要：

The wavefunction of the lithium positride (LiPs) ground state is calculated using an ab initio approach which uses a Gaussian basis with r(ij)(2) correlation factors. The energy of the LiPs ground state, -7.738 55 Hartree, has a total energy more negative than the sum of the positronium (-0.250 Hartree) and lithium (-7.478 04 Hartree) ground states. The ground state is therefore stable against dissociation into Li + Ps with a binding energy of -0.010 51 Hartree.
