【 摘 要 】

Tunneling time definitions are calculated in the adiabatic limit of strong field tunnel ionization by the exact solution of the Schrodinger equation in a static electric field. We find that all definitions give finite tunneling times. In addition, the short-range potential approximation agrees well with the exact solution as long as one stays sufficiently far from over-the-barrier ionization regime.
