Electric Nondipole Effect in Strong-Field Ionization
A. Hartung, S. Brennecke, K. Lin +10
Strong-field ionization of atoms by circularly polarized femtosecond laser pulses produces a donut-shaped electron momentum distribution. Within the dipole approximation this distr…

Direct Experimental Access to the Nonadiabatic Initial Momentum Offset upon Tunnel Ionization
S. Eckart, K. Fehre, N. Eicke +11
We report on the non-adiabatic offset of the initial electron momentum distribution in the plane of polarization upon single ionization of argon by strong field tunneling and show…
