Abstract
We report on investigations of time dependent autoionization of doubly exci ted magnesium atoms in a strong electric held. A narrow band laser excites one electron towards a 3s16k Stark state and, subsequently, the second elec tron is excited with a short laser pulse. The autoionizing electron yield s hows a stepwise decay which is detected by a streak camera with picosecond resolution. Quantum calculations are in good agreement with the experimenta l results.
