Abstract
The rate of growth of Lu177 into neutron-irradiated ytterbium has been measured by radioassay of lutetium fractions separated by ion-exchange techniques. Such measurements show the parent of Lu177 to be the 1.8 hour Yb; this latter nuclide is therefore Yb177. Confirmatory values of 3.71 ± 0.04 hours and 6.75 ± 0.05 days have been obtained for the half-lives of Lu176m and Lu177.Keywords
