  "abstract": "The total cross sections for the Gd-152(p,gamma)Tb-153 and Gd-152(p, n)Tb-152 reactions have been measured by the activation method at effective center-of-mass energies 3.47 <= E-c.m(eff) <= 7.94 MeV and 4.96 <= E-c.m(eff) <= 7.94 MeV, respectively. The targets were prepared by evaporation of 30.6% isotopically enriched 152Gd oxide on aluminum backing foils, and bombarded with proton beams provided by a cyclotron accelerator. The cross sections were deduced from the observed gamma-ray activity, which was detected off-line by an HPGe detector in a low background environment. The results are presented and compared with predictions of statistical model calculations. This comparison supports a modified optical proton+Gd-152 potential suggested earlier.",
