Measurements of Cross Section for 160Gd(n,2n)159Gd and 158Gd(n,p)158Eu Reactions at the Neutron Energies of 13.5,14.1 and 14.6MeV

  • The cross sections for (n, 2n) and (n, p) reactions were measured on Gadolinium isotopes at the neutron energies of 13.5—14.6MeV using activation technique. The cross section data for the reactions of 160Gd(n, 2n) 159Gd and 158Gd(n, p) 158Eu were reported.The cross sections of 160Gd(n, 2n) 159Gd reaction are (1940±83)mb, (2324±92)mb and (1983±77)mb at (13.5±0.2)MeV, (14.1±0.1)MeV and (14.6±0.2)MeV, respectively. The cross sections of 158Gd(n, p) 158Eu reaction are (1.9±0.1)mb, (2.1±0.1)mb and (3.5±0.1)mb at (13.5±0.2)MeV, (14.1±0.1)Mev and (14.6±0.2)MeV, respectively. The neutron fluences were determined by the cross sections of 93Nb(n, 2n) 92mNb reaction. The comparison was made between the present results and the previously published data.

Abstract: The cross sections for (n, 2n) and (n, p) reactions were measured on Gadolinium isotopes at the neutron energies of 13.5—14.6MeV using activation technique. The cross section data for the reactions of 160Gd(n, 2n) 159Gd and 158Gd(n, p) 158Eu were reported.The cross sections of 160Gd(n, 2n) 159Gd reaction are (1940±83)mb, (2324±92)mb and (1983±77)mb at (13.5±0.2)MeV, (14.1±0.1)MeV and (14.6±0.2)MeV, respectively. The cross sections of 158Gd(n, p) 158Eu reaction are (1.9±0.1)mb, (2.1±0.1)mb and (3.5±0.1)mb at (13.5±0.2)MeV, (14.1±0.1)Mev and (14.6±0.2)MeV, respectively. The neutron fluences were determined by the cross sections of 93Nb(n, 2n) 92mNb reaction. The comparison was made between the present results and the previously published data.
