Infrared Multiphoton Dissociation of UF6 in Supersonic Nozzle Reactor

Activation Energy for Isotope Exchange Reaction between 235UF5 Nanoparticles and 238UF6 Gas

“…The fluorine atom transfer reaction from 235 U-enriched UF 5 nanoparticles to natural isotopic UF 6 gas, was first found by Grigor'ev et al and has been studied experimentally and theoretically. ,− Since the transfer of the fluorine atom from 238 UF 6 to 235 UF 5 converts 235 UF 5 to 235 UF 6 , this reaction behaves as if 235 U and 238 U are exchanged between UF 5 and UF 6 . The investigation of the isotopic exchange reaction is very important for developing the molecular laser isotope separation (MLIS) of uranium − because it deteriorates the enrichment of 235 U in the product, UF 5 , in MLIS.…”

Experimental study of sealed off operation of a high repetition rate TEA CO2 laser

“…Laser radar [2], multi-photon induced chemistry including a heavy molecular excitation [3], and laser material processing [1] are some of the main applications of these lasers. In spite of enormous efforts since 1960s, and contrary to continuous wave CO 2 lasers, which play indispensable roles in present industry, high repetition rate TEA CO 2 lasers are far from being used extensively in usual industries.…”
