摘要：

Density functional theory calculations on Yb- using the Hartree-Fock system and the analogous Dirac-Hartree-Fock methods predict that Yb- is stable in the P-degrees-1/2 state. The electron affinity obtained after the correlation energy functionals used are calibrated against Ca- and Lu is 2 +/- 1 mHartree (54 +/- 27 meV). The calculations indicate that the P-degrees-3/2 state is unlikely to be bound due to spin-orbit coupling reducing its binding energy.
