    "abstract": "We present a convergent variational basis-set calculational scheme for\nelastic scattering of positronium atom by hydrogen atom in S wave. Highly\ncorrelated trial functions with appropriate symmetry are needed for achieving\nconvergence. We report convergent results for scattering lengths in atomic\nunits for both singlet ($=3.49\\pm 0.20$) and triplet ($=2.46\\pm 0.10$) states.",
