Abstract

Don C. De Vault and W. F. Libby1 and E. Segrè;, R. S. Halford and G. T. Seaborg2 have shown that the 4.5-hr. radiobromine transforms into the 18-min. isotope which is β-active, by the emission of soft γ-rays. Le Roux, Lu and Sugden3 find that this is the method of disintegration of at least 90 per cent of 4.5-hr. radiobromine. Segrè, Halford and Seaborg2 predicted that the γ-rays would be soft, and a large proportion would be internally converted.
