  In the framework of a systematic study of proton induced nuclear reactions on
lanthanides we have measured the excitation functions on natural cerium for the
production of 142,139,138m,137Pr, 141,139,137m,137g,135Ce and 133La up to 65
MeV proton energy using the activation method with stacked-foil irradiation
technique and high-resolution gamma-ray spectrometry. The cross-sections of the
investigated reactions were compared with the data retrieved from the
TENDL-2014 and TENDL-2015 libraries, based on the latest version of the TALYS
code system. No earlier experimental data were found in the literature. The
measured cross-section data are important for further improvement of nuclear
reaction models and for practical applications in nuclear medicine, other
labeling and activation studies.
