摘　　要：Employing the reaction microscope,the experiment of He^(2+)collisions on Ar was performed[1].We have measured fully momentum analyzed Ar^(3+) recoil ions and two ejected electrons as well as He+projectiles in coincidence with each other.Fully differential cross sections(seeing Fig.1)for electron transfer from the target to the projectile accompanied by the ejection of two additional target electrons were extracted.This is the first measuring fully differential cross section on the fivebody process which supplies the most rigorous test for the relative theories[2].To a large extent the data can be reproduced by an independent electron model.
