Abstract

A phenomenological analysis of the channel involving the production of three alpha particles in collisions of relativistic oxygen nuclei with protons is performed for the first time. It is shown that one-third of it is saturated by the decay of an excited nucleus 12C*, while the remaining part is due to direct Fermi breakup or the quasielastic knockout of one alpha-particle cluster from a loosely bound residual nucleus consisting of three alpha particles. The results obtained by simulating the decay of the excited system involving three alpha particles for an isotropic phase space describe experimental data satisfactorily at moderate values of the excitation energy (ΔE *<15 MeV).
