Isotope separation of 176Lu a precursor to 177Lu medical isotope using broadband lasers

Lithium isotope separation with tunable diode lasers.

A laser-isotope-separation study of lithium has been performed with two-step excitation involving UV laser radiation and a visible tunable-diode laser. The method yields a high degree of selectivity by tuning the narrow-linewidth diode laser to the D1 or D2 levels of the lithium atom. Selective laser excitation is simplified by the use of the tunable diode laser and the overall approach benefit...

Isotope Effects, Isotope Separation and Isotope Fractionation

Electrochemical isotope effect and lithium isotope separation.

A large electrochemical isotopic effect is observed upon the electrodeposition of lithium from solutions of propylene carbonate producing isotopically light metal deposits. The magnitude of fractionation is controlled by the applied overpotential and is largest close to equilibrium. Calculated partition function ratios for tetrahedrally coordinated lithium complexes and metallic lithium predict...

Laser isotope separation of uranium

A research effort was carried out at the Bhabha Atomic Research Centre (BARC), Mumbai, for developing laser-based techniques for enrichment of natural uranium to reactor-grade (2.5% to 3.0% U), with the potential to be economically scalable to industrial production. Three approaches – two molecular, namely CO2 laser-based approach and UF6-based approach, and one atomic, namely Atomic Vapour Las...

A MODEL STUDY OF LASER ISOTOPE SEPARATION BY PHOTOIONIZATION OR PHOTODISSOCIATION PROCESS

In this study, the selective photoexication of isotopic mixtures by laser light is investigated. Atomic and molecular methods are examined and rate equations are derived for both cases. Two and three step photoionization techniques are considered and rate equations are solved for ion yields. The molecular photodissociation process is also studied and the dependence of the dissociation produ...
