Abstract
Method and apparatus for separation of an isotope substance from a mixture of isotope substances such as UF.sub.6 by adiabatically decompressing the mixture in vaporous or gaseous form to cool the mixture to a temperature below 100.degree. K. and irradiating by an electromagnetic wave selectively absorbed by an isotope substance, passing the mixture after cooling and irradiating in a diffuser at a velocity greater than the speed of sound and decelerating to convert the velocity into pressure with reduced velocity of the mixture. The higher pressure results in substantial reduction in operating costs and capital investment.
