- Title
Resonance Levels of Neutrons in Silver Nuclei.

- Abstract
THE resonance absorption of neutrons by silver nuclei has been studied with a photo-neutron source by Kurtschatow and Schepkin1 and by us2. Continuing this work, we have now estimated the total width of the resonance levels effective for neutron capture which have their energy values lying in the continuous spectrum of the neutrons scattered in a thin paraffin layer. Using the formula of Breit and Wigner3 for the capture cross-section as a function of energy, and making some simplifying assumptions, we can evaluate the average spacing between adjacent levels in the energy region concerned, by giving a plausible value to the width of a single level.
