where t is the temperature in °C and the quoted error is the standard deviation. There is thus in this case no significant influence of the temperature upon the mass effect. Some previous investiga­ tions of molten LiN03 gave smaller values for the mass effect. The reasons for these apparent dis­ crepancies are discussed. A slight, but significant, anomalous enrichment of the light isotope is o...
