Abstract

Two-proton relative momentum distributions from the break-up channels ²³Al ²¹Na and ²²Mg?p+p+20Ne at an energy of 60-70 A MeV have been measured together with two-proton opening angles at the projectile fragment separator beamline (RIPS) in the RIKEN Ring Cyclotron Facility. The results demonstrate the existence of diproton emission component from single-step 2He for highly excited ²³Al and ²²Mg.
