Measurement of spallation cross sections for the production of terbium radioisotopes for medical applications from tantalum targets

摘要

We present new measurements of cumulative cross sections for the production of ~(139)Ce and ~(149)Tb by proton-induced spallation of tantalum foil targets at different proton energies between 300 and 1700 MeV, using the COSY synchrotron at FZ Juelich. Those measurements are presented in the context of the production of medically-relevant radioisotopes for medical applications.
