Abstract
We present a study of the ionization of the hydrogen atom by weak and strong static electric fields from the ground state and from some excited states. The under- and above-ionization barrier dynamical regimes are accurately computed for short and long times. The results are interpreted through the spectral density which emphasizes, for transitory regimes, the role of the resonances arising from the ground and from the lowest excited states. The observability of the dynamics is discussed.
