Abstract
We analyze tunnel ionization of a single atom based on the Wigner function over the classical phase space which inspires improved classical electron trajectories: these start with exit momenta based on the quantum momentum function and correspond very well to the subsequent quantum evolution. We derive an approximate analytic formula to reconstruct the tunnel exit time and exit momentum from electron momentum data that can be measured e.g. with a usual time-of-flight electron detector.
