147Eu decay scheme and 147Sm excited state structure

Using the experimental data on the differential-integral γ-coincidences the decay scheme of 147Eu has been constructed in which the levels 716,6; 1106,8; 1172,6; 1219,7; 1317,8; 1349,6; 1600,9; 1641,9 keV have been established for the first time in β-decay. The excitation by β-decay of the levels: 872,9; 1006,7; 1228,1; 1303,7; 1588,2; 1629,9 and 1658,4 keV have not been confirmed. Additionally for the states of 147Sm the spins, parities and the log ft of correspondent values have been determined. The correspondence between the experimental and calculated energies of the 147Sm - levels has been obtained in the framework of interactiong boson-fermion model. On the basis of the description of transition probabilities and log ft-values a conclusion about the necessity of taking into account in the operator of the transition an exchange terms has been drawn
