Production of 139Ce by proton-induced reactions on 141Pr and natLa

Excitation functions and production rates are presented for various Ce radionuclides formed in the bombardment of 141Pr and natLa with protons. Measurements were performed for 141Pr + p up to 100 MeV and for natLa + p up to 20 MeV. The possibility is investigated to utilize tandem targetry for the production of no-carrier-added 139Ce of high radionuclidic purity, having a Pr target in the higher energy slot followed by a La target in a lower energy slot. The results of this work are also compared with previous literature experimental data, where available, as well as with predictions by means of the geometry-dependent hybrid (GDH) model as implemented in the code ALICE-IPPE.
