摘要:

The isotopic effect occurring during evaporation of microgram samples of lithium chlorides has been studied. The isotopic ratios7Li/6Li show a time dependence variation corresponding to the Rayleigh distillation formula, but the fractionation factor observed is smaller than the one applied so far. Using an original method, the new value of this factor was found.
