Thermal desorption electron electron ionization mass spectra of puuified C60/C70 have been studied in a quadrupole mass spectrometry.The ionization method os very convenient and efficient in contrast to the Fast atom bombrdment. besides the observations of C60+, C70+ ions, many new fragment ions such as C58^2+, C56^2+ are also observed from TDEI mass spectrum .the ionization energies of C60. C70and their frament behaviors been discussed simply.
Key words: THERMAL DESORPTION, MASS SPECTROGRAPHY, CARBON ION, CHEMICAL IONIZATION SOURCE MASS SPECTROMETRY, FRAGMENTS, FAST ATOM BOMBARDMENT
