Abstract

Experiments of ²³Al and ²²Mg radioactive beams bombarding a ¹²C target at an energy of 60 ∼70 A MeV have been performed at the projectile fragment separator beamline (RIPS) in the RIKEN Ring Cyclotron Facility to study the two-proton emission from ²³Al and ²²Mg excited states, respectively. The trajectorie of the decay products, namely ²¹Na + p + p from ²³Al and ²⁰Ne + p + p from ²²Mg, are clean identified. The relative momentum and opening angle between two protons in the rest frame of three body decay channels are obtained by relativistic-kinematics reconstruction. The results demonstrate that there are some di-proton emission components from ²He cluster for the excited ²³Al and ²²Mg.
