Nonadiabatic tunnel ionization in strong circularly polarized laser fields: counterintuitive angular shifts in the
Abstract:
We perform time-dependent calculation of strong-field ionization of neon, initially prepared in 2p(-1) and 2p(+1) states, with intense near-circularly polarized laser pulses. By solving the three-dimensional time-dependent Schrödinger equation, we find clear different offset angles of the maximum in the photoelectron momentum distribution in the polarization plane of the laser pulses for the two states. We provide clear interpretation that this different angular offset is linked to the sign of the magnetic quantum number, thus it can be used to map out the orbital angular momentum of the initial state. Our results provide a potential tool for studying orbital symmetry in atomic and molecular systems.
