Abstract

Supersonic flow of a molecular gas under the appropriate conditions through an expansion nozzle, produces homogenous condensation of the gas. if the gas is vibrationally excited, the condensation is inhibited. Thus, selective vibrational excitation of an isotopic species in the gas provides a means of controlling the condensation of the gas. Such selective vibrational excitation may be readily accomplished by means of laser irradiation of the supersonically flowing gas. The controlled condensation in turn may be used as the basis of isotope separation and enrichment by subjecting the stream of gas and condensate particles to aerodynamic processes whereby the condensate particles are separated from the main flow of the gas.
