Abstract

An experiment of 22Mg and 20Ne beams bombarding on a 12C target at an energy of 60∼70 A MeV has been performed at the RIKEN projectile fragment separator (RIPS) in the RIKEN Ring Cyclotron Facility to study the two-proton correlated emission from 22Mg and 20Ne excited states. The two-protons momentum correlation functions have been obtained for 22Mg and 20Ne, respectively. The trajectories of the 22Mg decayed products (20Ne + p + p) were also measured to get the angular correlations between the two protons in Center of Mass of decaying system by relativistic-kinematics reconstruction. The results exhibit that 22Mg has the features of 2He cluster decay mechanism.
