Abstract

DURING recent years considerable controversy has taken place over the atomic weight of carbon, the values obtained by chemical methods and by density determinations ranging from 12.000 to 12.010. At the same time, the abundance of the rare isotope C13 first supposed to be about 1 in 400, has recently been estimated to be as high as 1 per cent.
