Abstract
The study of resonance scattering of neutron-capture gamma rays has been extended using 22 capture gamma sources and 57 scattering targets. About 50 resonance-scattering events have been observed in 23 elements and the effective cross sections evaluated. Some cases of complex spectra are described. The association of the scattering with nuclei in the region of closed shells is clearly shown. Problems of minimum observable cross sections are discussed and some further applications of the technique are suggested.
