Laser excitation of BCl3 and consequential collision-induced reaction with carrier gases

Abstract

A method is developed to demonstrate the laser excitation and consequential collision-induced reaction with carrier gases (G = He, N2, Ar, Xe) in isotope separation of BCl3. To investigate the mechanism of the transport process of excited molecules and the collision process with the carrier gases, the Lennard-Jones potential parameters of the molecule and the carrier gases, as well as the collision cross section σc and the repulsion distance parameter LR, are demonstrated. The transport equation (proposed by Eerkens in 2005) is used to study the transport mechanics of stimulated BCl3 molecules, including VT energy conversion and VV energy transfer caused by the collision of BCl3 molecules with the carrier gases during the supersonic pneumatic transportation, as de-excitation induced by transfer, dimer formation and dissociation, and so on.
