Emission of d, t,³He andα-particles from¹²C nuclei excited by intermediate energy photons

Abstract

Abstract. New GRAAL data on the fragmentation of carbon nuclei by photons at 800 -1500 MeV are discussed. In addition to previously published results for the proton and neutron emission probabilities at different multiplicities, preliminary results on the yields of heavier fragments as d, t, 3 He and α-particles are presented. The obtained results are compared with theoretical predictions and other fragmentation data measured in different reactions induced by photons, electrons and relativistic ions.
