Asymptotic behavior of scattering amplitudes in semi-classical and low energy limits
We study the semi-classical asymptotic behavior as \(h\to 0\) of scattering amplitudes for Schrödinger operators \(-()h^ 2\Delta +V.\) The asymptotic formula is obtained for energies fixed in a non-trapping energy range and also is applied to study the low energy behavior of scattering amplitudes for a certain class of slowly decreasing repulsive potentials without spherical symmetry.
