Carbon cluster ions produced by field evaporation from single-walled nanotubes (SWNTs), multiwalled nanotubes (MWNTs) and vapor grown carbon fibers (VGCFs) have been analyzed by mass spectrometry. The mass spectra observed under an ultra-high vacuum (UHV) showed that the singly charged C_<29>H_n and C_<32>H_n clusters were generated as common magic clusters for all samples. The mass spectra of C_<20>+ so far reported cannot be detected in an UHV conditions.

用质谱法对单壁纳米管（SWNTs）、多壁纳米管（MWNTs）和气相生长碳纤维（VGCFs）中场蒸发产生的碳团簇离子进行了分析。超高真空下的质谱研究表明，所有样品都产生了单电荷的C_<29>H_n和C_<32>H_n团簇，它们是普通的幻数团簇。迄今为止所报道的C_ +的质谱<20>在超高真空条件下是测不到的。
