Abstract
The (e, H) collision problem is treated using the multichannel quasiparticle method recently introduced by Grassberger and Sandhas. We derive single variable integral equations for the singlet and triplet transition amplitudes valid for scattering energies up toE≈8 eV and especially calculate the scattering lengths which are in good agreement with previous results found by variational methods.
