The mathematics of low-energy scattering from asymptotic power law potentials are examined to extract characteristic lengths of the scattering problem in the limit of low velocity. These are then used to characterize the limiting behavior of the scattering wave function, leading immediately to general, explicit, sufficiency conditions for quantum reflection for arbitrary gas and surface species.
