Measured charge-and mass-changing cross sections for the systems 4 He + 12 C, 4 He + 16 O, 4 He + 28 Si, and 4 He + 1 H in the energy range 70-220 MeV/u are presented. The cross sections were obtained via the attenuation method where a E-E scintillator telescope was used for particle identification. These new data

Measured cross sections for the production of the PET isotopes , and from carbon and oxygen targets induced by protons (40–220 ) and carbon ions (65–430 ) are presented. These data were obtained via activation measurements of irradiated graphite and beryllium oxide targets using a set of three scintillators coupled by a coincidence logic. The measured cross sections are relevant for the PET particle range verification method where accurate predictions of the emitter distribution produced by therapeutic beams in the patient tissue are required. The presented dataset is useful for validation and optimization of the nuclear reaction models within Monte Carlo transport codes. For protons the agreement of a radiation transport calculation using the measured cross sections with a thick target PET measurement is demonstrated.
