This thesis embodies a systematic investigation on the abundance variation of and Li^6/Li^7 ratios in synthetic and natural samples by mass spectrometric technique. The measurements of ratios were carried out with a 10", ...

One may now summarize the main findings of this work and also discuss a few additional points for further work. The first important result is that the critical exponent for the divergence of dR/dT in binary liquids has no ...
