【 摘 要 】

Synopsis The benchmarked Regge-pole method on the calculated low-energy electron elastic scattering total cross section (TCS) for C60through the measured electron affinity (EA) [1,2] is used to calculate TCSs for selected fullerenes, from C54through C240in the electron impact energy range 0.02 ≤ E ≤ 10.0 eV. From the characteristic dramatically sharp resonances representing long-lived ground state fullerene negative ion formation we extracted the binding energies (BEs) and compared them with the measured EAs, obtaining outstanding agreement.
