From: J-Matrix time propagation of atomic hydrogen in attosecond fields

Ionization spectra of H for different numbers of half cycles \(N_c\) and different field amplitudes \(E_0\). (a): \(E_0 = 0.1\), (b): \(E_0 = 1.0\), (c): \(E_0 = 1.5\). Please note, the diagrams contain different scalings of \(d\!P/d\!E\).
