-T中子诱发232Th(n,f)134Te裂变反应截面测量

he fission cross section of 232Th(n,f)134Te fission reaction induced by 14 MeV neutrons was measured precisely with the neutron activation technique. Neutron flux was tested on line by T(d,α)n reaction in the measurements and neutron energies were obtained by the cross section ratio of 90Zr(n, 2n)89Zr reaction to 93Nb(n, 2n)92mNb reaction. The values of the cross section are deduced to be 10.10±1.18、10.61±1.24 and 11.51±1.34 mb at neutron energies of 14.1±0.3、14.5±0.3 and 14.7±0.3 MeV, respectively.
