Calculation of Stark resonance parameters for valence orbitals of the water molecule

Atomic Physics 2016-11-23 v1

Abstract

An exterior complex scaling technique is applied to compute Stark resonance parameters for two molecular orbitals (1b11b_{1} and 1b21b_{2}) represented in the field-free limit in a single-center expansion. For electric DC field configurations that guarantee azimuthal symmetry of the solution the calculation is carried out by solving a two-dimensional partial differential equation in spherical polar coordinates using a finite-element method. The resonance positions and widths as a function of electric field strengths are shown for field strengths starting in the tunnelling ionization regime, and extending well into the over-barrier ionization region.
