摘要
Cross-sections for （n, 2n） reactions have been measured on stannum isotopes at the neutron energies of 13.5 to 14.6 MeV using the activation technique. Data are reported for the following reactions： ^112Sn（n, 2n）^111Sn, ^118Sn（n, 2n）^117Sn and ^124Sn（n, 2n）^123mSn. The neutron fluences were determined using the monitor reaction ^93Nb（n, 2n）^92mNb or ^27Al（n, α）^24Na. The results of present work were compared with data published previously.
