摘　　要：用活化法相对标准反应测量了(92)Mo（n，p）(92)Nbm反应截面，其能区为5～19MeV。测量中分析了低能中子的影响，采用恰当的方法有效地扣除了他们的干扰。特别是在17～19MeV能区，用空靶扣除了D－d低能中子的影响，得到了合理的截面走向。The cross sections of 92Mo(n,p)92Nbm, reaction are measured relatively to standard reactions using activation method, In neutron energy range from 5.to 19 MeV. The influence of low energy neutrons is considered very carefully in the whole measurement, and effective methods are used to deduct their interference. Especially in 17-19 MeV range, the empty tritium target is irradiated to subtract the influence of D-d neutrons from self-building D target, and a reasonable cross section tendency is obtained. A comparison is made between the present results and the published data.
