Electron affinity of neutral species
| EAneutral (eV) | Method | Reference | Comment |
|---|---|---|---|
| 1.910 ± 0.050 | LPD | Dresch, Kramer, et al., 1991 | Both dissociation and electron detachment? |
| 1.90 ± 0.20 | LPES | Snodgrass, Coe, et al., 1988 | Appears to be dissociation + electron detachment |
| <2.760 ± 0.020 | LPES | Tsukuda, Hirose, et al., 1997 | Stated electron affinity is the Vertical Detachment Energy |
| 2.50 ± 0.20 | NBAE | Bowen, Liesegang, et al., 1983 |
