We conclude molecular hydrogen is the stable form consistent with the lack of observed electrical and optical activity. Both H+ and Ho have complex surfaces, with some features sensitive to lattice distortion. The local minima are too small to give localised states when zero-point energy is included. We discuss our results in relation to earlier theories and to experiments on "normal" and "anomalous" muonium [{\ensuremath{\mu}}+e-].}, issn = {0378-4371}, url = {http://dx.doi.org/10.1016/0378-4363(83)90234-6} }
