Time Delay in Electron C60 Elastic Scattering in a Dirac Bubble Potential Model
Within the framework of a Dirac bubble potential model for the C60 fullerene shell, we calculated the time delay in slow electron elastic scattering by C60. It appeared that the time of transmission of an electron wave packet through the Dirac bubble potential sphere that simulates a real potential of the C60 cage exceeds by more than an order of magnitude the transmission time via a single atomic core. Resonances in the time delays are due to the temporary trapping of electron into quasi bound states before it leaves the interaction region.
