Investigation of γ radiation from 178Hf in the respective (n, n′γ) reaction

The spectra and angular distributions of gamma rays were measured in the reaction 178 Hf( n, n′γ ) induced by a beam of fast reactor neutrons. Data onmultipole mixtures in gamma transitions and a lot of new information about gamma transitions of energy 1.5 to 3.0 MeV were obtained. A comparison of these results with information known from the respective ( n, γ ) reaction made it possible to refine the schemes of deexcitation of 178 Hf levels at energies above 1.5 MeV, to determine more precisely features of these levels, and to introduce new levels and rotation bands at excitation energies of about 2MeV.
