Time Delay in Electron-C60 Elastic Scattering in a Dirac Bubble Potential Model (1809.08880v1)
Published 24 Sep 2018 in physics.atm-clus
Abstract: 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.
