An additional channel opens for photoionization of atom A by an electromagnetic field if it traverses a gas of atoms B resonantly coupled to this field. We show that this channel, in which A is ionized via resonant photoexcitation of B with subsequent energy transfer to A through two-center electron correlations and which is very efficient when A and B constitute a bound system, can strongly dominate the ionization of A also in collisions where the average distance between A and B exceeds the typical size of a bound system by orders of magnitude.
