The destruction cross-section for 22.5 and 50 keV C1- , for 10 and 50 keV C8 1- and for 50 and 75 keV C60 1- clusters in collisions with H2 has been measured by an attenuation method. The destruction of the cluster anions is dominated by electron detachment rather than fragmentation and is of the order of the geometric cross-section. The cross-sections vary little with bombarding energy.
