Isotope separation is demonstrated following the selective infrared laser-induced photodissociation of van der Waals clusters in a free jet. Irradiation of a natural abundance mixture of SF/sub 6/ isotopomers diluted in argon with a 20-W cw CO/sub 2/ laser gives overall enrichment factors in excess of 1.1. By adjusting the wavelength one can either enrich or deplete the center of the free jet in any one of the sulfur isotopes. Furthermore, unselective photodissociation of clusters can be used to enhance the separation of isotopes in a recently reported selective condensation method. 8 references, 3 figures.
