Abstract
A redetermination of the absolute yield G of ferrous sulfate oxidation by 2‐Mev cathode rays has been made with improved accuracy. The corrections for backscattering and charge transfer have been critically re‐examined, the correction for absorption of energy in the windows has been determined experimentally and an improved method of determining the energy of the rays is described. The value of G is 15.45±0.11 and is independent of radiation intensity.
