Cross section measurements of (n, 2n), (n, p) and (n, α) reactions on gadolinium isotopes in the neutron energy range of 13.5 to 14.8 MeV
Cross sections for (n, 2n), (n, p), and (n, α) reactions have been measured on gadolinium isotopes at the neutron energies from 13.5 to 14.8 MeV using the activation technique in combination with high-resolution gamma-ray spectroscopy. Neutrons were produced via the 3 H(d, n) 4 He reaction using solid TiT. The neutron fluences were determined using the monitor reactions 93 Nb( n , 2n) 92m Nb and 27 Al(n, α) 24 Na. The neutron energy in this measurement was determined by cross section ratios for the 90 Zr(n, 2n) 89m+g Zr and 93 Nb(n, 2n) 92m Nb re-actions. Data are reported for the following reactions: 152 Gd(n, 2n) 151 Gd 154 Gd(n, 2n) 153 Gd, 160 Gd(n, 2n) 159 Gd, 156 Gd(n, p) 156 Eu, 157 Gd(n, p) 157 Eu, 158 Gd(n, p) 158 Eu, and 158 Gd(n, α) 155 Sm. The cross sections are discussed and compared with the experimental data found in the literature.
