Study of the vibrational photochemical reation, of UF₆+HCl and its isotopic selectivity

Abstract

The photochemical vibrational reaction of UF6+HCl was investigated by exciting the ternary overtone of 3V3 of UF6 in an intracavity CO laser system. It was found that the rate of the laser‐driven reaction was much greater than that of the thermal reaction and this photochemical process had an isotopic selectivity. The uranium isotope enrichment factors measured in experiments were around 1,007 in a single step.
