Abstract

The ⁹⁹Mo isotope can be produced by photonuclear technique via ¹⁰⁰Mo (Γ, n) ⁹⁹Mo reaction. A bremsstrahlung converter used for its realisation, is being simultaneously a source of photoneutrons. Therefore, under irradiation of a target from the natural molybdenum by mixed Γ, n-radiation one can expect an increase of the ⁹⁹Mo yield at the expense of an additional ⁹⁸Mo (n, γ) ⁹⁹Mo channel. The method and device providing a possibility of the ⁹⁹Mo yield measurement in a target from natural molybdenum at its placing in a moderator of neutrons, and also without it are developed. Experimental study was conducted at accelerator LU-40m of NSC KIPT in the electron energy range 30...60 MeV. It is shown, that moderator application increases the ⁹⁹Mo yield up to 30 %. Computer simulation of the experiment on the basis of PENELOPE-2008 and GEANT 4 9.4 program systems was carried out. The results obtained are in a good agreement with the experimental data.
