MEASUREMENT OF FRAGMENT PRODUCTION CROSS SECTIONS IN THE C-12+C-12 AND C-12+Au-197 REACTIONS AT 62 A MeV FOR HADRONTHERAPY AND SPACE RADIATION PROTECTION

Over the last twenty years, there has been a renewed interest in nuclear fragmentation studies for both hadrontherapy applications and space radiation protection. In both fields, fragmentation cross sections are needed to predict the effects of the ions nuclear interactions within the patient's and the astronaut's body. Indeed, the Monte Carlo codes used in planning tumor treatments and space missions must be tuned and validated by experimental data. However, only a limited set of fragmentation cross sections are available in literature, especially at Fermi energies. Therefore, we have studied the production of secondary fragments in the (12)c+(12)c and C-12+Au-197 reactions at 62 A MeV. In this work, the measured He-4 cross sections angular distributions at four selected angles are presented and compared.
