Resolving discrepancies in Zr-90(p,γ)Nb-91 data
Published: March 2025 Simon-Robertson
Nucleosynthesis of proton-rich isotopes of elements beyond iron remains a question to astrophysical models. In particular production of Mo/Ru isotopes remains a challenge, as the unusually high solar abundances of these isotopes cannot be reproduced by models. 90Zr(p,γ)91Nb is one of the reactions in the production path of 92Mo and previous experimental data showed a substantial discrepancy in the measured cross section. This work resolves the disagreement confirming the lower experimental cross section. Learn more
