摘要：

Accurate EF (1)Sigma(g), (3)Sigma(u) and h(3)Sigma(g) state adiabatic potentials are computed for internuclear distances up to atomic units. All the energies are more accurate by a fraction of a wave number from existing results. Scattering lengths for collisions of 1S and 2S hydrogen atoms are evaluated. These differ significantly from earlier results. This is because for some states the scattering length is very sensitive to even small changes in the potential.
