Isotope separation by multiphoton dissociation of molecules with high-power CO2 laser radiation. IV. Enrichment with 33S by irradiation of cooled SF6 gas

An investigation was made of the selective dissociation of ³³SF₆ in a natural isotopic mixture in the temperature range 123–293°K. By cooling the gas, it was possible to achieve a degree of separation in the dissociation products q(33/32) ≈ 5 for the dissociation of ³³SF₆( in the optimal temperature range 170–190°K. The measured values of the dissociation parameters indicate that it is quite feasible to develop an efficient ³³S enrichment process yielding weighable amounts.
