Projectile energy loss and final charge state distribution in Xeq+–C60 collisions at low energy

The projectile final charge state distribution and the energy loss have been studied in frontal collisions between Xeq+ ions (q=15–30) at low velocity (v=0.28 a.u.) and C60 molecule. In our experiment, the frontal collisions are separated from the peripheral collisions by analysing the kinetic energy of the outgoing projectile in coincidence with the recoil ions (stable C60r+ or fragments of C60) and the number of ejected electrons. The energy losses are found equal to 760±150, 900±150 and 1300±300 eV for Xe15+, Xe25+, Xe30+ incident ions respectively.
