Ionization of stark states with half-cycle pulses: Interference effects in the continuum
A detailed study of oscillations in the ionization spectrum of a Stark state in sodium excited by half-cycle pulse was carried out. Full-quantum calculations revealed oscillations in the DKD spectrum that can be explained with a 1D semiclassical model as interference effects between two dominant trajectories leading to the same final energy. On the other hand, the UKD spectra showed no oscillations due to a larger angular spread of the wave function as it scatters from the core. For the downhill state, the dependence of the oscillations on the length of the pulse was outlined.
