摘要: A robust potential which embeds fully the vital core polarization interaction has been used in Regge-pole method to explore low-energy electron scattering from C60, Eu and Nb through total cross sections (TCSs) calculation. From characteristic dramatically sharp resonances TCSs manifesting negative ion formation these systems, we extracted binding energies (BEs) for C60 −, Eu− Nb− anions. Our BE − ground state is outstanding agreement with measured affinity (EA) of [1]. For anionic our BEs are compared EAs [2-4].
