dc.description.abstract | When atoms or molecules are exposed to strong short-pulse infrared radiation, ionization as well as "frustrated tunneling ionization"can occur, in which some of the nearly freed electrons recombine into the initial ground or an excited bound state. We analyze the ellipticity dependence of the relative signals that are predicted in a single-active-electron (SAE) approximation, the validity of which is checked against a parameter-free multielectron R-matrix (close-coupling) with time-dependence approach. We find good agreement between the results from both models, thereby providing confidence in the SAE model potential to treat the process of interest. Comparison of the relative excitation probabilities found in our numerical calculations with the predictions of Landsman et al. [A. S. Landsman, New J. Phys. 15, 013001 (2013)NJOPFM1367-263010.1088/1367-2630/15/1/013001] and Zhao et al. [Y. Zhao, Opt. Express 27, 21689 (2019)OPEXFF1094-408710.1364/OE.27.021689] reveals good agreement with the former for short pulses. For longer pulses, the ellipticity dependence becomes wider than that obtained from the Landsman et al. formula, but we do not obtain the increase compared to linearly polarized radiation predicted by Zhao et al. | |
