Abstract

Multiphoton ionisation of Mg was studied with an excimer laser (XeCl, X=308nm). The laser intensity dependence of the number of ions indicates that the lowest order two photon process that have enough energy to reach the first ionisation limit, failed to dominate the ionisation of magnesium for some unknown reason. A 3 photon resonance with some autoionising states was proposed to explain this anormal phenomena.
