Title: Direct Experimental Probe of the On-Site Coulomb Repulsion in the Doubly Charged Fullerene Anion C702-

Abstract

Vibrationally resolved photoelectron spectra were obtained for cold C70- and C702-. Accurate values for the first and second electron affinities (EA’s) of C70 were measured as 2.765 ± 0.010 and eV, respectively, establishing that C702- is an electronically stable dianion in the gas phase. The difference between the first and second EA (2.745 eV) provides a direct experimental measure for the onsite coulomb and exchange interactions between the two excess electrons in C702-. Strong electron correlation effects were also observed between the two excess electrons in C702-.
