摘　　要：用大液体闪烁探测器和飞行时间法,相对于^(197)Au测量了0.7—1.4MeV能区天然Nb的中子辐射俘获截面.在0.5—2.0MeV能区,对^(93)Nb的辐射俘获截面进行了理论计算.The radiative capture cross section of natural Nb with respect to that of gold in the 0.7-1.4MeV energy range was neasured using a large liquid scintillator detector and the time-of-flight method. In the 0.5-2.0MeV neutron energy range, the radiative capture cross section for 03Nb was calculated. The experimental and calculated results were discussed.
