Experiments to determine the yields and bremsstrahlung flux-averaged cross-sections σ(Еγmax) of photonuclear reactions on the natural Mo targets were performed on the beam from the electron linear accelerator LUE-40 with the use of the γ-activation technique. The bremsstrahlung end-point energies were in the range Еγmax = 35…80 MeV. The bremsstrahlung quantum flux was calculated with the program GEANT4.9.2 and, in addition, was monitored using the 100Мо(γ, n)99Мо reaction. Calculations of the yields and average cross-sections σ(Еγmax) for photonuclear reactions on stable Mo isotopes were computed using the σ(Е) cross-sections from the TALYS1.95 code (for the level density model LD1). A comparison of experimental and calculated cross-sections σ(Еγmax) for reactions 92Мо(γ, 2n)90Мо and 92Мо(γ, pn)90Nb was performed.

The bremsstrahlung flux-averaged cross-sections σ(E γmax ) and the cross-sections per equivalent photon σ(E γmax ) Q were first measured for the photonuclear multichannel reaction 27 Al(γ, x) 22 Na at end-point bremsstrahlung gamma energies ranging from 35 MeV to 95 MeV. The experiments were performed with the beam from the NSC KIPT electron linear accelerator LUE-40 with the use of the γ-activation technique. The bremsstrahlung quantum flux was calculated with the program GEANT4.9.2 and, in addition, was monitored by means of the 100 Mo(γ, n) 99 Mo reaction. The flux-averaged cross-sections were calculated using the partial cross-section σ(E) values computed with the TALYS1.95 code for different level density models. Consideration is given to special features of calculating the cross-sections σ(E γmax ) and σ(E γmax ) Q for the case of the final nucleus 22 Na production in the 27 Al photodisintegration reaction via several partial channels x: nα + dt + npt + 2n 3 He + n2d + 2npd + 2p3n.

“…Experimental study of copper photodisintegration cross-sections has been carried out through measurements of the residual γ-activity of the irradiated sample, which enabled one to obtain simultaneously the data from different channels of photonuclear reactions. This technique is well known and has been described in a variety of papers concerned with the investigation of multiparticle photonuclear reactions, e.g., on the nuclei 27 Al [22,23], 93 Nb [24][25][26], 181 Ta [1,27].…”

The bremsstrahlung flux-averaged cross-sections σ(Eγmax) for the photonuclear 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 in the range of bremsstrahlung end-point energies Eγmax = 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-line γ-ray spectrometric technique. The calculation of the flux-average cross-sections σ(Eγmax) th was carried out using the cross-section σ(E) values from the TALYS1.95 code with the 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, 63 Cu(γ, 2n) 61 Cu are systematically higher than the theoretical estimates in the TALYS1.95 code. The obtained σ(Eγmax) supplement the data of different laboratories for the case of reactions (γ, n) and (γ, 2n). For the reaction 63 Cu(γ, 3n) 60 Cu, the values of σ(Eγmax) were measured for the first time.
