A method for isotope separation

Creators

Description

For separating uranium isotopes in the UF6 compound, a laser radiation of 16 μm is used which stimulates the Q-branch of the v3-band of the sup(235)UF6. The spectrum width of the laser radiation corresponds at most to the isotope shift. The radiation intensity is so strong that its absorption reaches the saturation region. The time of radiation and the time for the physical and chemical separation are inferior to the rotational relaxation time. (DG)

Abstract (German)

Zur Trennung von Uranisotopen bei der Verbindung UF6 ist eine Laserstrahlung von 16 μm vorgesehen, die den Q-Zweig der v3-Bande des sup(235)UF6 erfasst. Die spektrale Breite der Laserstrahlung entspricht maximal der Isotopieverschiebung. Ihre Intensitaet ist so gross, dass deren Absorption den Saettigungsbereich erreicht. Die Strahlungsdauer und die Zeit fuer die physikalische oder chemische Abtrennung sind kleiner als die Rotationsrelaxationszeit. (DG)
