摘　　要：We have investigated the single capture with simultaneous single ionization in He2+ collisions with argon bymeans of reaction microscopes[1]. Here, we report the dependence of the azimuth angle (φe) of the relatively high-energy electrons (kinetic energy > 20 eV) on the transversal recoil momentum (pr⊥) in single capture with doubleionization process for 30 keV/u He2+ collisions with Ar. It is noted that the relatively high-energy electrons mainlyresult from binary encounter (BE) between the target electrons and the projectiles for the present reaction channel.
