Stabilization of Autoionizing States in Crossed Magnetic and Electric Fields

POSTER

Abstract

We demonstrate by numerical analysis of a zero-range potential model describing a negative ion in crossed magnetic and electric fields the existence of autoionizing states. We observe that with the increasing electric-field strength the lifetime of those states increases, reaches its maximum value, and then starts decreasing rapidly. Such a stabilization has been observed before for the so-called electric-field-induced resonances [1] but, to our knowledge, has never been recognized for autoionizing states. [1] K. Krajewska and J.
