Gamma cascades in gadolinium isotopes

Abstract

The compound nucleus model is employed to calculate the $$\gamma $$ γ decay after neutron capture by the gadolinium isotopes $$^{155}$$ 155 Gd and $$^{157}$$ 157 Gd. The respective $$\gamma $$ γ cascades are analyzed for possible use in rare-event searches like $$0\nu \beta \beta $$ 0 ν β β decay as neutron-veto for neutron energies in the range from 0.1 keV to 10 MeV.
