Abstract
We report the mass spectrometric investigation on fullerene derivatives C60CH2, C60RH , C60R2(R = C6H5 CO-) and C60On under the 308nm laser ablation. In the negative ion mass spectra of C60CH2, C60R2 and C60On odd-numbered clusters C-57,C-55, C-53, C-51 are observed clearly in addition to the even-numbered fullerene fragment ions, while for the monoadduct C60 RH,, odd-numbered species can not be detected. In the positive ion channel, the fragmentation patterns of the three derivatives are similar
