After astatine (0) was mixed with 1 3 1 1 2 containing carrier I , , the sample was analyzed by means of radiogaschromatography and the peaks due to I 2 , Atl and At2 were observed. Further, the boiling points were estimated from the retention volume in terms of the semi-empirical theory on gas chromatography. The boiling points of I 2 , Atl and At2 were 457 + 2 , 4 8 6 ± 2 and 503 ± 3 K, respectively. The boiling point of At2 obtained in the present work is far smaller than that expected by the extrapolation of lighter halogens.
