C60 particles were formed by a C60 vapor source equipped with an 241Am ionizer, and their mobility was measured using a differential mobility analyzer (DMA). Two distinct peaks for the C60 monomer and the C60 dimer were observed in the mobility spectra. When the measured mobility was compared with theoretical mobilities for several isomers of the C60 dimer, the C60 dimer was suggested to have the geometric structure of a [2+2] 66/66 cycloadduct C60 dimer. Selective formation of the [2+2] C60 dimer was also suggested when the peak profile for the C60 dimer was analyzed using the transfer function for the DMA. The formation mechanism of the [2+2] C60 dimer in the gas phase is discussed.
