A non-adiabatic model is employed to investigate the H-H
scattering at low temperatures. Unlike molecular-orbital calculation technique,
no separate calculations are required to obtain the potential energies of
electrons in the field of hadrons. This model generates the non-adiabatic
effective potential automatically. The coefficients of van der Waals and
higher-order potentials are estimated in the present model and are found to be
in very good agreement with the corresponding standard values. The s-wave
singlet and triplet scattering lengths and thermal-average total triplet
cross-section at 2 are reported and compared with the existing
theoretical and experimental predictions.
