Photonuclear Reactions on Bypassed Nuclei 84Sr and 92Mo

Abstract

The yields of photonuclear reactions on mixtures of natural isotopes of strontium and molybdenum that result in the formation and decay of bypassed nuclei 84Sr and 92Mo are measured and compared to theoretical results obtained using the TALYS code and calculations in the combined model of photonucleon reaction (CMPR). The need is demonstrated to consider isospin splitting in cases of photoproton reactions. The yields of the 92Mo(γ,p)91mNb, 84Sr(γ,p)83Rb reactions that make the main contribution to the formation and decay of 84Sr and 92Mo in the p-process of nucleosynthesis differ from the TALYS and CMPR results by several hundred percent.
