A Jost function description of zero-energy resonance and transparency effects in elastic collisions

Under certain circumstances, an elastic cross section at very low energies could differ by orders of magnitude above or below any reasonable estimate. The first case occurs near a zero-energy resonance, while the second one is akin to the well-known Ramsauer-Townsend effect. In spite of their intrin...
