| Popis: | We unambiguously identify, in experiment and theory, a previously overlooked holographic interference pattern in strong-field ionization, dubbed "the spiral", stemming from two trajectories for which the binding potential and the laser field are equally critical. We show that, due to strong interaction with the core, these trajectories are optimal tools for probing the target \textbf{after} ionization and for revealing obfuscated phases in the initial bound states. The spiral is shown to be responsible for interference carpets, formerly attributed to direct above-threshold ionization trajectories, and we show the carpet-interference condition is a general property due to the field symmetry.
