Abstract
The wave function for hydrogen in the Stark effect (or for the negatively anharmonic oscillator) with an outgoing‐wave boundary condition, constructed in Langer‐Cherry f__JWKB form, is continued back to the origin. The asymptotic expansions for Re__E and Im__E__ are determined by the requirement that the wave function be regular at the origin to zeroth and first order in the exponentially small parameter that characterizes Im__E__. One __f__JWKB function turns out to be the Rayleigh‐Schrödinger perturbation theory wave function.
