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

摘要

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.
