151Eu(n,γ)152m1Eu reaction cross-section measurement at the neutron energies of 1.12, 2.12, 3.12 and 4.12 MeV

The 151Eu(n,γ)152m1Eu reaction cross-section at the neutron energies (En) of 1.12, 2.12, 3.12 and 4.12 MeV was determined by using activation and off-line γ-ray spectrometric technique. The mono-energetic neutrons of 1.12–4.12 MeV were generated from the 7Li(p,n) reaction by using the proton beam energies of 3–6 MeV. The 197Au(n,γ)198Au reaction cross-section was used as the neutron flux monitor. The 151Eu(n,γ)152m1Eu reaction cross-section was also calculated by using computer code TALYS 1.6 and compared with the experimental data to check its validity. The Eu(n,γ) reaction cross-section is important for the safety of the fast reactor and conventional fission reactor.
