We propose a modification of the selective two-step photoionization technique which greatly improves its efficiency. A third species with a strong resonance transition is added to the mix of isotopes which it is desired to separate. Incident optical energy is radiatively and collisionally trapped in this catalytic species. Selective ionization of excited step one species is accomplished by long-range ionizing collisions.
