Proton induced reactions on 114Sn and 120Sn targets at energies up to 18 MeV

TL;DR

This study measures proton-induced reaction cross sections on tin isotopes up to 18 MeV, providing new experimental data and comparing results with theoretical calculations, enhancing understanding of nuclear reactions on tin.

Contribution

First experimental cross sections for specific reactions on 114Sn and 120Sn, and comparison with Talys1.95 calculations, including isomeric ratio measurements.

Findings

Good agreement with previous data and Talys1.95 for most reactions.

Discrepancies in 120Sn(p,α)117m,gIn reactions at higher energies.

Measured isomeric cross section ratios as functions of proton energy.

Abstract

We measure cross sections of proton-induced reactions on tin up to energies of 18 MeV using the stacked-foil activation technique, and report first experimental values for 114Sn(p,{\alpha})111In, {^{120}}Sn(p,{\alpha})117gIn, and 114Sn(p,x)113Sn reactions. Measured cross sections have been compared to existing experimental values and numerical calculations based on Talys1.95. Our data are in good agreement with all previous experiments, and also with Talys1.95 results except for 120Sn(p,{\alpha})117m,gIn reactions where the numerical calculations are shifted to higher energies. We also measure isomeric cross section ratios for 117m,gIn and 120m,gSb pairs as functions of the incident proton energy.
