Abstract
PROF. G. HEVESY and Hilde Levi submit two tables, one showing the power of absorption, determined by them, of some rare earth elements for neutrons and another giving the periods of decay and relative intensity of the resulting radioactive elements, as determined by various investigators. Discrepancies in the published data appear to be due to the presence of small amounts of impurities.
