Measurement of 93 Nb(n,2n)92g+mNb cross section was carried out on Cockcroft-walton accelerator at CIAE.Neutron flying through the collimator arrived at the Nb sample placed in the center of the moderator.Then neutrons produced by 93 Nb(n,2n)92g+mNb reached the 3 He tube after moderating in polyethylene.The signal from the tube entered the preamplifier and then entered the Flash ADC.The gate was set to 200microseconds,and 2n neutrons were recorded.The results were showed in Table 1.
