Separation of U235 and U238 isotopes by converting a mixture of these isotopes to organic compounds or to silicon compounds and then irradiating the isotope compounds selectively to change their chemical (and/or physical) properties, thereby to facilitate separation. In a preferred embodiment of the invention the uranium compounds are selected from the group having a chemical moiety R bonded directly to the U atom, the U-R bond having a fundamental, overtone, or combination virbational absorption frequency between 900 and 1100 cm-1. The selected U mixture is then irradiated with a frequency-selective CO2 laser. |
