    "abstract": "The energies at geometries close to the equilibrium for the e$^+$BeO and\ne$^+$LiF ground states were computed by means of diffusion Monte Carlo\nsimulations. These results allow us to predict the equilibrium geometries and\nthe vibrational frequencies for these exotic systems,and to discuss their\nstability with respect to the various dissociation channels. Since the\nadiabatic positron affinities were found to be smaller than the dissociation\nenergies for both complexes, we propose these two molecules as possible\ncandidates in the challenge to produce and detect stable positron-molecule\nsystems.",
