The Radiative Strength Function Using the Neutron-Capture Reaction on 151,153Eu

Radiative strength functions in 152,154Eu nuclei for γ‐ray energies below 6 MeV have been investigated. Neutron capture for incident neutron energies <1eV up to 100 keV has been measured for 151,153Eu targets. Properties of γ decay of neutron resonances in 152,154Eu nuclei are examined. The results of measurements are compared to outcome of simulation of γ cascades based on various models for the radiative strength function. Comparison between experimental data and simulation suggests existence of the low‐energy resonance in these two nuclei.
