Abstract：
The cross sections for (n,2n) reaction are measured on Neodymium isotopes at the neutron energies of 13.5-14.6MeV using activation technique.The cross section data for the reactions of ¹⁵⁰Nd(n,2n)¹⁴⁹Nd,¹⁴⁸Nd(n,2n)¹⁴⁷Nd and ¹⁴²Nd(n,2n)¹⁴¹Nd are reported.The cross sections of ¹⁵⁰Nd(n,2n)¹⁴⁹Nd reaction are 2037±85,1737±68 and 1657±65mb at 13.5±0.2,14.1±0.1 and 14.6±0.2MeV respectively.The cross sections of ¹⁴⁸Nd(n,2n)¹⁴⁷Nd reaction are 1394±58,1416±54 and 1956±76mb at 13.5±0.2,14.1±0.1 and 14.6±0.2MeV respectively.The cross sections of ¹⁴²Nd(n,2n)¹⁴¹Nd reaction are 1501±59,1623±62 and 1764±111mb at 13.5±0.2,14.1±0.1 and 14.6±0.2MeV respectively.The neutron fluences are determined by the cross sections of ⁹³Nb(n,2n)^92mNb reaction.The comparison between the present results and the previously published data is made.
