A simple photoionization technique for enriching a particular isotope of mercury in a naturally-occurring mixture employing an isotopically pure radiation source separately optimized for 253.7 nm. and 404.7 nm. emission, respectively. A vessel is provided for containing the naturally occurring mercury. This vessel may be part of either a flow or closed system. The radiation source brings the isotope from the 61S0 ground state to the 63P1 state wherein the nitrogen gas deactivates the isotope to bring the isotope to the long-lived 63P0 state. Thereafter, the source optimized at 404.7 nm. brings the isotope to the 73S1 state. At this level the atom may be easily photoionized either by a laser or a powerful visible incoherent radiation source.
