Abstract

A scintillation spectrometer in ring geometry was used to study the gamma rays accompanying the inelastic scattering of fast neutrons on Na, Mg, Mn, Fe and I. The energies of the gamma rays were in most cases arranged into the cascade decay schemes of excited nuclei. Some of the transitions, which had not yet been described, were also found. These are the lines (2147±21) keV for Mg25, (2135±22) keV, (2750±40) keV, (3040±50) keV and (3200±50) keV for Mn55 and a series of other gamma rays emitted during the interaction of fast neutrons with I127, which are given in the paper.
