Cross-section measurement of ( n ,2 n ) reactions for Nd isotopes induced by 14 MeV neutrons

Cross-sections of the ( n ,2 n ) reactions for neodymium (Nd) isotopes induced by 14 MeV neutrons were measured in this work by using the activation and relative methods. The measured cross-sections of the 150 Nd( n ,2 n ) 149 Nd, 148 Nd( n ,2 n ) 147 Nd, and 142 Nd( n ,2 n ) 141 Nd reactions were 1854 ± 81, 1789 ± 119, and 1559 ± 98 mb, respectively, at a neutron energy of 14.2 ± 0.2 MeV, and 1485 ± 74, 1726 ± 85, and 1670 ± 119 mb, respectively, at 14.9 ± 0.2 MeV. The results were compared with the experimental values from the reported literature, with the evaluated data from the ENDF/B-VII.1, CENDL-3.1, and JENDL-4.0 libraries, and with the curves calculated by the Talys-1.8 code.
