Abstract Carbon cluster ions generated by laser evaporation have been reacted with atoms (Ar) and molecules (O2, D2). In order to vary the reaction conditions for the cluster ions two gas inlets at different locations have been added to the cluster source. Addition of D2 increased the line width in the TOF-spectrum indicating the appearance of reaction products of the type CmDn. Both O2 and D2 proved very effective in removing the odd numbered carbon cluster ions in the vicinity of C60. Application of O2 produced a significant effect: depending on the gas pressure it reacted with small cluster ions forming products like CnO+ and CnO2 +. Such reaction channels are not found for n〉12 thus indicating a change in cluster geometry. Another sequence of experiments has been undertaken by adding Ar atoms to the carbon cluster ions. Some stable ionic reaction products like ArC+,..., ArC4 +, ArC5 + can be detected. It is known from previous studies that the ArC+ is a stable ion with an dissociation energy of about 1 eV.
