    "abstract": "Calculations of the positron-Li system were performed using the Stochastic\nVariational Method and yielded a minimum energy of -7.53208 Hartree for the L=0\nground state. Unlike previous calculations of this system, the system was found\nto be stable against dissociation into the Ps + Li$^+$ channel with a binding\nenergy of 0.00217 Hartree and is therefore electronically stable. This is the\nfirst instance of a rigorous calculation predicting that it is possible to\ncombine a positron with a neutral atom and form an electronically stable bound\nstate.",
