Tunneling time in attosecond experiment, a theoretical model with a comparison for H-atom — •Ossama Kullie — University of Kassel, Fachbereich 10, Heinrichplett str. 41, 34132 Kasel

Tunneling and tunneling time are hot debated and very interesting due to their fundamental role in the quantum mechanics. The measurement of the tunneling time in today’s attosecond and strong field (low-frequency) experiments, despite its controversial discussion, it offers a fruitful opportunity to understand time measurement and the time in quantum mechanics. In [1,2] we suggested a model and derived a simple relation to calculate the real tunneling time, to calculate the real tunneling time. In this work [3] we discuss and analyze the model against an experimental result for H-atom obtained recently by Sainadh et al [4]. For H-atom the model shows a good agreement with the experimental result as previously for He-atom [1]. However there are crucial points for higher intensities, in particular where the electric field strength is higher than the atomic filed strength, we will discuss this for the case of H-atom. [1] O.
