摘要：

Absolute partial and total cross sections for the electron impact ionization of C60 have been measured using a novel approach for the absolute calibration. The results obtained reveal not only an anomalous large parent ion cross section (as compared to the other ionization channels), but also anomalies for the production of multiply charged parent and fragment ions. This special behavior has its origin in the specific electronic and geometric structure of C60. Semiclassical calculations for singly charged ions support the measured data. © 1995 The American Physical Society.
