✦ Synopsis
The averaged intensities of high-energy gamma rays in copper have been measured with a Ge(Li) detector after the capture of 10-60 keV neutrons. The capture spectra represent the average strengths of transitions from a large number of resonances. They bear no relation to the thermal result, thus supporting the view that the latter proceeds through a non-compound nucleus mechanism. The ground state transition does not dominate the keV capture spectrum and the intensities indicate the presence of an Ey 3 energy dependence.
