【 摘 要 】

We present the absolute differential electron emission cross section of coronene under fast bare O-ion impact. The results show some features which cannot be explained by simple ion-atom type collision result. The difference of the energy and angular distribution data with that for CH4and Ne may indirectly indicate the influence of collective excitation. We have performed the CB1 calculation for comparison.
