    "abstract": "We report scattering lengths for the singlet Sigma g +, triplet Sigma u + and\nquintet Sigma g + adiabatic molecular potentials relevant to collisions of two\nmetastable (n=2 triplet S) helium atoms as a function of the uncertainty in\nthese potentials. These scattering lengths are used to calculate experimentally\nobservable scattering lengths, elastic cross sections and inelastic rates for\nany combination of states of the colliding atoms, at temperatures where the\nWigner threshold approximation is valid.",
