Synopsis A two body fragmentation experiment of NeAr dimer by 480 eV electron impact was performed. By recon-structing the momenta of Ne + ion, Ar + ion and one electron, the 2D coincidence map between Kinetic energy release and electron energy is obtained, from which two islands are observed. It is found that, Interatomic Coulombic Decays induced by Ne + Ar ion and Ar + Ne ion can both take place in our experiment, as well as Radiative Charge Transfer. This is different from X ray in which only one decay process is dominant in one incident energy.
