We have measured two-proton momentum and angular correlations for the {sup 23}Al excited states from the {sup 23}Al radioactive beam on a {sup 12}C target at an energy of 60approx70 A MeV at the projectile fragment separator beamline (RIPS) in the RIKEN Ring Cyclotron Facility. The decay products, namely {sup 21}Na+p+p from {sup 23}Al are clean identified. The relative momentum and opening angle between two protons in the rest frame of three body decay channels demonstrate that there are some diproton emission components from {sup 2}He cluster for the excited {sup 23}Al.
