Abstract
For the reaction 138Ba(n, n′γ) induced by a beam of fast reactor neutrinos, the gamma spectrum, the angular distributions of gamma radiation, and its linear polarizations are measured, along with the half-lives of the excited states involved. The known diagram of energy levels and gamma transitions is supplemented. The multipole-mixture ratios δ are found for many transitions between the energy levels in question, and half-lives are determined for some excited states.
