“…In addition, we can easily prepare projectile ions such as metal atomic ions, small cluster ions, etc., where it would be very difficult to prepare the corresponding neutral species for C 60 ϩ ϩM scattering. We have studied scattering of atomic ions of neon, 22 lithium, sodium, and potassium, 23,24 boron, 25 carbon, 26 nitrogen, 27 oxygen, 28 fluorine, 25 a variety of transition metals 25,29 as well as Mn 2 ϩ , CO ϩ , and C 2 ϩ . 25 We are able to extract energetics for en-dohedral penetration, substitution reactions, and fragmentation reactions.…”
