Abstract

The Eu153(n,2n)Eum1,m2,g152 cross section was measured by means of the activation technique at three neutron energies in the range 13–15 MeV. The quasimonoenergetic neutron beam was formed via the H3(d,n)He4 reaction, in the Pd-300 Neutron Generator at the Chinese Academy of Engineering Physics (CAEP). The activities induced in the reaction products were measured using high-resolution γ-ray spectroscopy. The cross section of the population of the second high-spin (8) isomeric state was measured along with the reaction cross section populating both the ground (3) and the first isomeric state (0). Cross sections were also evaluated theoretically using the numerical code TALYS-1.8, with different level density options at neutron energies varying from the reaction threshold to 20 MeV. Results are discussed and compared with the corresponding literature.
