摘要：

The diffusion quantum Monte Carlo (DQMC) method simulating the Green's function to quadratic accuracy is applied to the computation of the positronium affinity of the lithium atom. The result suggests that the positronium lithium system, [e(+)---Li-] is a stable entity with respect to positronium detachment as well as positron dissociation.
