The WKB Approximation without Divergences
arXiv:quant-ph/9710004 · doi:10.1007/BF02435726
Abstract
In this paper, the WKB approximation to the scattering problem is developed without the divergences which usually appear at the classical turning points. A detailed procedure of complexification is shown to generate results identical to the usual WKB prescription but without the cumbersome connection formulas.
