Abstract
An isotope separation is conducted by diluting a mixture containing the object isotope compound being enriched with an inert diluent gas which is transparent to the irradiated infrared rays; condensing the isotope compounds together with the inert diluent gas on a cold plate and irradiating specific infrared rays absorbed only by the object isotope compound to selectively excite the object isotope compound.

A method of separating isotopes using an infrared laser, comprising:
- diluting a gaseous isotopic mixture of compounds from which a specific isotope compound is to be separated from all other isotope compounds with an inert diluent gas which is transparent to the infrared radiation from said laser;
- condensing said isotopic mixture with the diluent gas as a condensed layer on a cold surface;
- and
- irradiating said condensed gases with infrared radiation from said laser of a wave length which selectively excites the isotope compound desired to be separated, thereby achieving the desired separation by the migration of the energized isotope compound toward the cold surface.

A method of separating .sup.11 B compounds from an isotopic mixture of boron compounds with laser infrared light, which comprises:
- diluting a gaseous isotopic mixture of boron compounds containing .sup.11 B from which said .sup.11 B compound is to be separated with an inert diluent gas which is transparent to the infrared radiation from said laser;
- condensing said isotopic mixture with the diluent gas as a condensed layer on a cold surface;
- and
- irradiating said condensed layer with infrared radiation from said laser of a wavelength which selectively excites said .sup.11 B isotopic compound, thereby achieving the desired separation by the migration of the energized .sup.11 B isotope compound toward the cold surface.
