Abstract
THE determination of neutron resonance energies of nuclei which are made radioactive after neutron capture is possible by utilizing their activities, and several such cases are known; for example, silver, rhodium, iodine, indium, gold, etc. But in the cases of nuclei which are not made radioactive, it is much more difficult to discover the existence of resonance neutron groups and to determine their energies. H. A. Bethe1 has suggested several methods for such cases, but no noteworthy results have been obtained except that of A. E. Dowing and C. D. Ellis2.
