Abstract
The energy spectrum, the angular distributions, and the linear polarizations of gamma radiation emitted by 158Gd are measured in the (n, n′γ) reaction induced by fast reactor neutrons. The known diagram of levels and gamma transitions is extended. The multipole-mixing ratio δ is found for many gamma transitions between levels with known spin-parity values.
