    "abstract": "We verify that the van der Waals interaction and hence all dispersion\ninteractions for the hydrogen molecule given by: W\"= -{A/R^6}-{B/R^8}-{C/R^10}-\n..., in which R is the internuclear separation, are exactly soluble. The\nconstants A=6.4990267..., B=124.3990835 ... and C=1135.2140398... (in Hartree\nunits) first obtained approximately by Pauling and Beach (PB) [1] using a\nlinear variational method, can be shown to be obtainable to any desired\naccuracy via our exact solution. In addition we shall show that a local energy\ndensity functional can be obtained, whose variational solution rederives the\nexact solution for this problem. This demonstrates explicitly that a static\nlocal density functional theory exists for this system. We conclude with\nremarks about generalising the method to other hydrogenic systems and also to\nhelium.",
