Berakdar, J. and Kirschner, J., Kluwer Academic/Plenum Publishers, New York, USA 2001This work aims at visualizing the role of the inelastic electron-electron relaxation time in metal clusters. We develop a quantum mechanical model for the description of inelastic electronic collisions from metal clusters and apply it to the ionization of C60 by low-energy electrons. The results show evidently that the measured spectrum for the production of C60+ depends strongly on the screening of the electron-electron collisions. The value of the screening length we obtain is in accord with previous studies on the relaxation in metal clusters.
