    "abstract": "We study the dynamics of the Potassium atom in the mid-infrared, high\nintensity, short laser pulse regime. We ascertain numerical convergence by\ncomparing the results obtained by the direct expansion of the time-dependent\nSchroedinger equation onto B-Splines, to those obtained by the eigenbasis\nexpansion method. We present ionization curves in the 12-, 13-, and 14-photon\nionization range for Potassium. The ionization curve of a scaled system, namely\nHydrogen starting from the 2s, is compared to the 12-photon results. In the\n13-photon regime, a dynamic resonance is found and analyzed in some detail. The\nresults for all wavelengths and intensities, including Hydrogen, display a\nclear plateau in the peak-heights of the low energy part of the Above Threshold\nIonization (ATI) spectrum, which scales with the ponderomotive energy Up, and\nextends to 2.8 +- 0.5 Up.",
