Laser photolysis of UF{sub 6} molecules
- State Research Center of Russian Federation 'Troitsk Institute for Innovation and Fusion Research', Troitsk, Moscow Region (Russian Federation)
Studies of the photophysical and photochemical processes accompanying the photolysis of UF{sub 6} molecules in the field of UV and IR laser radiation are analysed. The characteristic features of the electronic and vibrational absorption spectra are discussed. The excited states and transitions as well as the molecular deactivation and dissociation channels are identified. The influence of secondary processes on the quantum yield and the photolysis yield is determined. The photolysis of UF{sub 6} molecules in the presence of chemically active reagents and buffer gases is considered. The isotopically selective laser photolysis of UF{sub 6} molecules as a method for the separation of uranium isotopes, as well as other prospects for the application of the laser photolysis of UF{sub 6} molecules in nuclear power engineering, are discussed.
