A process and an apparatus for separating rare sulfur isotopes by isotope specific dissociation of gaseous sulfur hexafluoride by two infrared lasers which produce laser beams which irradiate the gas in an interactive region of a reaction cell. The gas, which has been cooled to 150 DEG K, is initially irradiated with a pulsed laser whose wave-length is continuously variable, the laser being tuned to a sharp resonance in the region of the Q branch of the ???3 oscillation of the desired isotope to be separated and which has an intensity of 2 to 3 MW/cm<2> in the interactive region. The gas is then subjected to the radiation of a second laser whose emission is shifted by 4 to 6 cm<-1> toward longer waves with respect to the first laser and whose fluency in the interactive region is 3 to 6 J/cm<2>. <IMAGE> |
