Abstract: (Elsevier)
Low-energy quantities like the scattering length and effective range parameter range parameter are direetly derived from the threshold behavior of the scattering amplitude for Schrödinger Hamiltonians with short-range and Coulomb-type interactions. The possibility of zero-energy resonances and zero-energy bound states of the underlying Hamiltonian is explicitly taken into account. No spherical symmetry of the interaction is assumed.
