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...
متن کاملIsotope Effect in Diffusion
A derivation of the classical jump rate I' for tracer diffusion aimed at a clear expression for the mass dependence of the frequency factor v is presented. The derivation is effected without using the usual collective normal coordinates which usually combine the masses in a complicated way. v depends explicitly on the mass of the surrounding host atoms (as well as on the tracer-atom mass) if th...
متن کاملThe Isotope Effect in Superconductors
We review some aspects of the isotope effect (IE) in superconductors. Our focus is on the influence of factors not related to the pairing mechanism. After summarizing the main results obtained for conventional superconductors, we review the effect of magnetic impurities, the proximity effect and non-adiabaticity on the value of the isotope coefficient (IC). We discuss the isotope effect of Tc a...

متن کاملInfluence of Secondary Decay on Isotope-ratio Temperature Measurement
In intermediate energy heavy ion collisions, nuclear fragments are emitted from highly excited systems. Production of these particles appears to be dominated by their phase space, and can be described by statistical physics. Thus, temperature, a basic quantity in statistical physics, can be addressed experimentally. Two methods have been most commonly used to measure nuclear temperatures, both ...
