Abstract
THROUGH the kindness of Messrs. Krishnan and Gant, I have been able to examine the radiations from a silver foil of 20 mgm./cm.2 bombarded with 9 Mv. deuterons, using the method of critical absorption previously adopted in the case of the fission products of uranium1. For the quantum radiations from the 6·8-hour body, a palladium foil of 24 mgm./cm.2 was considerably more transparent than a foil of molybdenum of only 14 mgm./cm.2. This is in agreement with the findings reported above, although it does not allow a decision to be made as to whether the K-radiations of silver or cadmium are involved (it is hoped, later, to use an absorber containing ruthenium in order to examine this point more closely).
