We will present the absolute cross sections for electron impact induced
removel of C_2 molecule from the fullerene ions C_60^q+ in the charge
states q=1...3. The measurements were performed employing the Giessen
electron-ion crossed-beams set-up. The cross sections were determined
from the respective threshold up to an electron energy of 1 keV. The
measurement will be compared with available data and theoretical
calculations.
