| Abstract: | The excited states of154Gd populated by theβ-decay of154Eu (T 1/2=8.5y) have been studied. With a HPGe-NaI (T1) Compton suppression spectrometer and a HPGe-NaI(T1) coincidence circuitυ-ray singles spectra, coincidence spectra and theγ-γ directional correlational functions have been obtained. The deduced mixing ratios of multipolarities are presented. The energy levels and the relativeB(E2) values of the variousγ-transitions in154Gd nucleus have been calculated both in the IBA model and it's extended version with boson surface delta interaction (BSDI). |
