    Graphical Abstract
    • Abstract
  • Eu activity is obtained from the 154 Sm sample irradiated by reactor neutrons and through chemical separation by ion exchange technique. Activity is measured using 4πβ γ coincidence apparatus and photon counting is performed applying HPGe and small area planar Ge detectors. From these measurements the absolute intensities for the γ rays emitted from decay of 156 Eu are determined. The uncertainties of experimental results are less than 2%.
