“…For a given number x of emitted neutrons, the relationship between the mean cross section and the mass number has been derived from data taken in the 0.2-1GeV energy range. The data have been compiled and analyzed in [61], which reports xn) = 0.187A0.684 exp [ -37A-0.924(~l)s'4] mb. ( 14)…”

An analysis of the total photoabsorption cross section for nuclei ranging from 4He up to 238U has been performed in the energy range 0.2-1.0 GeV. Mean total photoabsorption cross sections have been obtained by summing up the contributions from partial photoreactions, and found to follow an A1-dependence in the 0.2-1.0 GeV range. A review of the available total photoabsorption cross section data is also presented. Comparisons have been made with cross section values calculated by considering both the quasi-deuteron and π-meson photoproduction mechanism of primary nuclear photointeraction.

“…In this energy range, only simple reactions, such as (γ,n), (γ,2n), and (γ,p), can take place [5,[9][10][11], with the compound reaction mechanism playing a dominant role. At higher energies, the nuclear reaction processes become more complex [12][13][14][15]; this means that the measurement and analysis of experimental data related to, for example, reaction cross sections and/or reaction yields can help ex-pand our understanding of specific aspects (for example, reaction mechanisms and reaction channel effects) and provide useful nuclear data for application purposes. Therefore, the study of multiparticle reactions occurring via bremsstrahlung radiation with end-point energies above the giant dipole resonance (GDR) region, that is, >30 MeV, is gaining an increasing amount of attention [16][17][18][19].…”

This study measured the yields of the radionuclides 82Sr, 83(m+g)Sr, 85mSr, 85gSr, 87mSr, 81(g+0.976m)Rb, 82mRb, 83gRb, 84(m+g)Rb, and 86(m+g)Rb produced in natSr(γ,xnyp) multiparticle reactions with bremsstrahlung end-point energies of 55-, 60-, and 65-MeV. The bremsstrahlung radiations were generated using the 100-MeV electron linac at the Pohang accelerator laboratory, Korea, and the reaction yields were derived from the induced activities measured using off-line γ-ray spectrometry. To obtain accurate experimental results, we made the necessary γ-ray interference corrections. The experimental results were compared with the theoretical predictions obtained using the TALYS-1.95 statistical nuclear model code. The calculations were performed using six different level-density models to ascertain which model best fitted the experimental results. The dependence of the reaction yield on the incident bremsstrahlung energy and on the number of nucleons emitted by the photonuclear reactions was also investigated.
