EA (eV) Method Reference Comment
2.310 ± 0.010LPESGoebbert, Khuseynov, et al., 2011ground state neutral is triplet; singlet state 0.64 eV up
2.31070 ± 0.00060N/AGarand, Yacovitch, et al., 2008Singlet state 0.654 eV up
2.289 ± 0.018LPESZengin, Persson, et al., 1996Imply that Oakes, Jones, et al., 1983 missed EA due to too low energy photons and wrong polarization
1.848 ± 0.027LPESOakes, Jones, et al., 1983see Zengin, Persson, et al., 1996 for reinterpretation
