Comment on "Weyl's theory and the complex-rotation method applied to phenomena associated with a continuous spectrum"

Abstract

Recent computations of complex-energy resonance poles by Rittby, Elander, and Br\"andas for a $V(x)=(\frac{1}{2}{x}^{2}\ensuremath{-}J){e}^{\ensuremath{-}\ensuremath{\lambda}{x}^{2}}+J$ model potential are compared with results found by a recently developed alternative technique using Milne's method. Differences in the resulting behavior of the pole string are discussed.
