CROSS-SECTIONS OF PHOTONEUTRON REACTION natMo(γ,xn)93mMo AT THE BREMSSTRAHLUNG ENERGY UP TO 95 MeV

Abstract

The photoproduction of the 93mMo nucleus on natural molybdenum was studied using the electron beam of the LUE-40 linac RDC “Accelerator” NSC KIPT. Measurements were performed using the activation method and off-line γ-ray spectrometric technique. For the natMo(γ,xn)93mMo reaction the experimental flux-averaged cross-sectionϭ(Eγmax)m at the bremsstrahlung end-point energy range of 38…93 MeV was first time determined. The theoretical values of the yields Ym,g(Eγmax) and flux-averaged cross-sections(Eγmax)m,g for the natMo(γ,xn)93m,gMo reactions were calculated using the cross-sections ϭ(Eγ) from the TALYS1.96 code for different gamma strength functions and level density models. The comparison showed strong discrepancies between the experimental values and the theoretical results of (Eγmax)m.
