摘要
In a recent work, we derived a formula for the elastic s-wave phase shifts for deep potentials with attractive tails vanishing faster than 1/r(2) asymptotically [Phys. Rev. A 84, 032701 ( 2011)]. As an addendum to that work, we reformulate its key result, i. e., the formula for the scattering phase shift delta(0), in such a way that the contributions independent of the short-range influence of the full potential are explicitly expressed in terms of the amplitudes for transmission through and quantum reflection by the nonclassical region of the potential tail.
