摘要：

In a recent paper, Drewello et al. [T. Drewello, W. Kratschmer, M. Fieber-Erdmann and A. Ding, Int. J. Mass Spectrom. lon Processes, 124 (1993) R1] reported a temperature dependent ionisation cross section for the formation of C-60(2+) in their photoionisation dynamic studies on C60 using synchrotron radiation. To check this, the ratio of ion intensities of C-60(2+) to that of C60 was determined as a function of temperature of C60 samples using a Knudsen effusion mass spectrometer. Our results indicate the absence of any temperature dependence of cross section for the formation of C-60(2+) in the temperature range of measurement (600-800 K) using electron impact ionisation.
