FORMATION AND FENOMENOLOGICAL DESCRIPTION OF BREMSSTRAHLUNG BEAM FOR PHOTONUCLEAR PROCESSES

Within the framework of the developed analytical model for description of the isotope production by bremsstrahlung radiation, the three key phenomenological parameters of the process have been established. Those parameters determine the total yield and volumetric distribution of the products of a photonuclear reaction with dominating giant dipole resonance (GDR) in a target. The applicability conditions as well as the accuracy of the phenomenological description of a flux of the above-threshold bremsstrahlung photons are studied. The form of description of a reference bremsstrahlung spectrum for analytical calculation of the photonuclear processes is proposed. The conditions and accuracy of its reproduction at an electron accelerator are investigated
