摘　　要：The flux-averaged cross-sections<σ(E_(γmax))>for the reactions^(65)Cu(γ,n)^(64)Cu,^(63)Cu(γ,n)^(62)Cu,^(63)Cu(γ,2n)^(61)Cu,and^(63)Cu(γ,3n)^(60)Cu have been measured within the bremsstrahlung end-point energy E_(γmax)range of 35–94 MeV.The experiments were performed with the electron beam from the NSC KIPT linear accelerator LUE-40 with the use of the activation and off-lineγ-ray spectrometric techniques.Theoretical calculation of the flux-average cross-sections<σ(E_(γmax))>_(th)was conducted using the cross-sectionσ(E)values from the TALYS1.95 code,run with default options.It is shown that the experimental average cross-sections for the reactions^(65)Cu(γ,n)^(64)Cu,^(63)Cu(γ,n)^(62)Cu,and^(63)Cu(γ,2n)^(61)Cu are systematically higher than the theoretical estimates based on the TALYS1.95 code.The obtained<σ(E_(γmax))values supplement the data of different laboratories for the(γ,n)and(γ,2n)reactions of^(63)Cu and^(65)Cu.For the reaction^(63)Cu(γ,3n)^(60)Cu,the values of<σ(E_(γmax))>were measured for the first time.
