Notes

1Theoretical values Cohen and Schneider, 1974.
2From elastic scattering of Ne+ by Ne Mittman and Weise, 1974. A similar value (D00 = 1.35 eV Connor and Biondi, 1965, Frommhold and Biondi, 1969) from spectral line profiles in a Ne afterglow (dissociative recombination radiation of neon) is given by Connor and Biondi, 1965, Frommhold and Biondi, 1969. From ab initio theory Cohen and Schneider, 1974 derive De = 1.17 eV Cohen and Schneider, 1974.
