Study of cluster structures of excited states for the light nuclei He, Li and Be in three-body photodisintegration processes. Application for the excited states of the 6He nucleus

The method used to investigate the cluster structures of excited states for the light nuclei He, Li and Be in three-body photodisintegration processes is described. As an application we present the experimental program on the Yerevan synchrotron for the photodisintegration of 7Li target, the production and decay of the 6He isotope and the study of the two-cluster (tritons) structures of excited states. In particular, the properties of the detectors used in the setup, as well as the precision and simulation of the measured values are presented.
