Electron affinity determinations
| EA (eV) | Method | Reference | Comment |
|---|---|---|---|
| 2.400 ± 0.030 | N/A | Peppernick, Gunaratne, et al., 2010 | Stated electron affinity is the Vertical Detachment Energy; B |
| 2.30177 ± 0.00087 | ZEKE | Arnold and Neumark, 1994 | B |
| 2.33 | LPES | Kitsopoulos, Chick, et al., 1990 | B |
