Description

On the basis of data on differential-integral coincidences the 146Eu→146Sm decay scheme is constructed. It consists of 68 levels, 22 of them have been introduced for the first time. Spins, parities and lg ft for excited levels of 146Sm are determined. Within the model of interacting bosons in which proton and neutron bosons are distinguished, energies and quantum characteristics of excited levels of 146Sm and reduced probabilities of E2-, M1-transitions are calculated. 19 refs.; 1 fig.; 5 tabs
