Adk ionization
WebThe ADK or PPT ionization rates used in this work contain the R-dependent ionization potential, and this does contribute in part to the non-Franck-Condon effect demonstrated therein. We also extend the analysis of non-Franck-Condon ionization to cir- cular polarization, and to several wavelengths covering the TI and MPI regimes. ... WebIt is clear that the ADK rates significantly overestimate the numerically calculated static ionization rates when the scaled field strength is near or above 1.0 (the barrier-suppression regime) for hydrogen atoms. Our goal in this paper is to find an empirical formula that can extend the ADK rates from the tunnelling ionization region to the
