Notes

1Potential data for the 1Sigma+ ground state from total scattering cross-section measurements Neumann and Pauly, 1968; see also Schlier and Vietzke, 1969. Neumann and Pauly, 1968 give also potential parameters for the 3Sigma+ excited state (De = 0.031 eV Neumann and Pauly, 1968, re = 6.2 Angstroms Neumann and Pauly, 1968) which arises from the same atomic products 2S + 2S.
