Abstract
In the Stark effect for the inverted δ-function potential, there are two kinds of field-induced resonances: the resonance stemming from the bound state supported by the bare potential, and a doubly infinite family of resonances originating from the continuum threshold. In this paper, we derive asymptotic expressions for the real and the imaginary parts (positions and halfwidths) of all these resonances as functions of the applied electric field, and then numerically track their behavior with changing field strength.
