Electron affinity determinations
| EA (eV) | Method | Reference | Comment |
|---|---|---|---|
| 2.765 ± 0.020 | LPES | Wang, Woo, et al., 2006 | cooled to 70 K from electrospray |
| 2.6760 ± 0.0010 | LPD | Brink, Andersen, et al., 1995 | Cooled in ring - extrapolated to "cold" value |
| 2.55 ± 0.21 | LPES | Palpant, Otake, et al., 1999 | Vertical Detachment Energy: 2.74 eV |
| 2.74321 | IMRE | Boltalina, Sidorov, et al., 1994 | ΔGea(660 K) = 2.15 kcal/mol > C60 |
| 2.720 ± 0.050 | IMRE | Boltalina, Sidorov, et al., 1993 | |
