Electron affinity determinations
| EA (eV) | Method | Reference | Comment |
|---|---|---|---|
| 2.60 ± 0.20 | LPES | Ohara, Koyasu, et al., 2003 | |
| 2.60 ± 0.20 | LPES | Cheshnovsky, Yang, et al., 1987 | EA given is Vertical Detachment Energy. Adiabatic EA est as up to 1 eV smaller |
| >2.99997 | LPD | Liu, Zhang, et al., 1986 | EA given is Vertical Detachment Energy. Thought to be considerably greater than adiabatic. |
