Study of the light nuclei cluster structures in three-body photodisintegration reactions. Application for the excited states of 6He nucleus

Abstract

An experimental program for the study of the cluster structures of excited states for the light nuclei of He, Li and Be in three-body photodisintegration processes is proposed. The investigations will be realized with 6Li, 7Li and 9Be targets in seven photodisintegration reactions. As an application, the photodisintegration of 7Li nuclei into the (t+t+p) final state with excitation and decay of neutron-rich 6He nucleus into the (t+t) channel is considered. The full Monte-Carlo simulation of the experiment is done with a special impact on the study of experimental setup performance, concerning the photon and excited states energy resolutions. The experiment will be performed on the bremsstrahlung photon beam of the Yerevan Electron Synchrotron.
