Abstract

The total cross sections for the $^{120}\mathrm{Te}(p,\ensuremath{\gamma})^{121}\mathrm{I}$ and $^{120}\mathrm{Te}(p,n)^{120}\mathrm{I}$ reactions have been measured by the activation method in the effective center-of-mass energies 2.47 MeV$ \ensuremath{\leqslant} {E}_{\mathrm{c}.\mathrm{m}.}^{\mathrm{eff}} \ensuremath{\leqslant} 7.93$ MeV and $6.44 \mathrm{MeV} \ensuremath{\leqslant} {E}_{\mathrm{c}.\mathrm{m}.}^{\mathrm{eff}} \ensuremath{\leqslant} 7.93 \mathrm{MeV},$ respectively. The targets were prepared by evaporation of $99.4%$ isotopically enriched $^{120}\mathrm{Te}$ on aluminum and carbon backing foils, and bombarded with proton beams provided by the FN tandem accelerator at the University of Notre Dame. The cross sections and $S$ factors were deduced from the observed $\ensuremath{\gamma}$ ray activity, which was detected off-line by two Clover HPGe detectors mounted in close geometry. The results are presented and compared with the predictions of statistical model calculations using the codes NON-SMOKER and TALYS.
