The total cross sections for the {sup 120}Te(p,{gamma}){sup 121}I and {sup 120}Te(p,n){sup 120}I reactions have been measured by the activation method in the effective center-of-mass energies 2.47 MeV {<=} E{sub c.m.}{sup eff} {<=} 7.93 MeV and 6.44 MeV {<=} E{sub c.m.}{sup eff} {<=} 7.93 MeV, respectively. The targets were prepared by evaporation of 99.4% isotopically enriched {sup 120}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 {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.
