| contents | We show experimentally and theoretically that vortex-shaped structures in the photoelectron momentum distribution can be observed for atoms interacting with a single intense elliptically polarized laser pulse. Our analysis reveals that these spiral structures are the result of destructive interference of two dominant photoelectron vortex states, which are released into the continuum by strong-field ionization. An electron born into one of those states is temporarily delayed near the atomic core by the combined atomic and laser potential, leading to fast changes in the phase delay with energy for photoelectrons in these vortex states. Our results open the door to studying electron dynamics of vortex states in strong-field ionization. |
