Formation cross sections of nuclei with (n, 2n) reactions

Formation cross sections of nuclei with (n, 2n) reactions 1 first-author 1 1 1 2 2 Shanghai Institute of Nuclear Research, the Chinese Academy of Sciences, Shanghai 201800 Shanghai Institute of Nuclear Research, the Chinese Academy of Sciences, Shanghai 201800 Shanghai University, Shanghai 201800 Shanghai University, Shanghai 201800 Neutron activation technique is used to measure the formation cross sections on even-even target nuclei with 14.6 MeV (n, 2n) reactions. The absolute values are calculated by using an integrated pre-equilibrium statistical model. The result gives a general good fit to the experimental data and shows the existence of shell effect on the cross sections. Problems related to the effect are discussed.
