ABSTRACT:
A method of producing carbon--13 by multiphoton decomposition of C.sub.3 F.sub.6, said material containing carbon--12 and carbon--13 isotopic species, comprising irradiating gaseous C.sub.3 F.sub.6 in a reaction chamber at a pressure below 10 Torr with a laser beam at a frequency in the range of 950 to 1020 wavenumbers and providing a minimum fluence of 1 joules per sq. cm. and passing the material through a physical separation stage to obtain a .sup.13 C.sub.2 F.sub.4 product.
