Abstract
Effective range theory is applied to the description of annihilation processes in positron-atom scattering. It is found that the result Z(eff)(k)similar tok(2)l[a+o(k(2))] is obeyed for the lth partial wave irrespective of whether the scattering potential includes long-range polarization potentials or not.
