Isotope separation process by transfer of vibrational energy
Description
This process consists in exciting A molecules by absorption of a pulsed light beam, then in exciting until their dissociation X molecules, present in several isotopic forms, by a vibrational transfer between the A molecules and the X molecules, the A molecules having a dissociation energy greater than that of the X molecules, the duration and energy of the light pulses being such that the absorption time by the A molecules is less than the excitation time of the X molecules and the temperature conditions such that the thermal width of the vibration rays is at the most near the isotopic difference between the resonance rays of the two isotopic varieties

Ce procede consiste a exciter des molecules A par absorption d'un faisceau lumineux pulse, puis a exciter jusqu'a leur dissociation des molecules X, presentes sous plusieurs formes isotopiques, par un transfert vibrationnel entre les molecules A et les molecules X, les molecules A presentant une energie de dissociation superieure a celle des molecules X, la duree et l'energie des impulsions lumineuses etant telles que le temps d'absorption par les molecules A soit inferieur au temps d'excitation des molecules X et les conditions de temperature etant telles que la largeur thermique des raies de vibration soit au plus voisine de l'ecart isotopique entre les raies de resonance des deux varietes isotopiquesAdditional details
