Abstract：
According to the regulation of growing and decay of artificial radioactive nuclide, a formula used to calculate the cross section of isomerous state with characteristic gamma-ray of ground state in a special case was deduced. And the cross sections of ¹²⁸Te(n,2n)^127mTe reaction induced by neutrons around 14MeV were measured and calculated by using the activation technique and the formula deduced above. The experimental results were (737±69) and (853±82)mb at the neutron energies of (14.1±0.2) and (14.6±0.3)MeV, respectively. The samples wrapped in cadmium foil were irradiated in order to avoid the effect of (n, γ) reaction induced by thermal neutron. The neutron energies in these measurements were determined by the method of cross-section ratios between ⁹⁰Zr(n,2n) ^89m+gZr and ⁹³Nb(n,2n) ^92mNb reactions, and the neutron fluencies were determined by using the monitor reaction ⁹³Nb(n,2n) ^92mNb.
