Calculation of scattering amplitudes near resonance
A. P. Kochkin
Abstract:
A method is proposed for directly calculating the coefficients in the principal term of the expansion of scattering amplitudes near resonance without knowledge of the phase shifts. In the anisotropic case it can also be used to calculate the dampings of levels that would be truly bound states if their energy did not lie within other bands.
