(color online) The t– curve and the electron probability density on the detector for the photodetachment of the H⁻ ion in the oscillating electric field with different electric field strength. The oscillating electric field frequency a.u. and the phase φ = 0. The detector is localized at the point a.u. The black line represents the down orbit and the red line denotes the up orbit. The left column is the t– curve that the detached electron can reach the detector, while the right column is the corresponding electron probability density on the detector. The electric field strength is denoted in each plot.
