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.
