Decay of Tb-152 and E0 and M1+E0 transitions in Gd-152

The decay of Tb-152 has been investigated by means of measurements of singl es gamma-spectra and gamma-gamma coincidence experiment, The 704 transition s were observed, of which 347 were identified to the decay of Tb-152 for th , first time. Using the more precise and full data about intensities of gam ma-transitions and previously reported conversion electron intensities the EO or M1 + E0 multipolarities were established for several transitions. The revised decay scheme consists of about one hundred excited levels from whi ch 46 levels were introduced for the first time.
