| dc.description | The electron affinity (EA) of europium has been measured using laser photodetachment electron spectroscopy. The EA of Eu(<sup>8</sup>S<sub>7/2</sub>) was determined to be 1.053 ± 0.025 eV. The data also show that Eu<sup>−</sup> has at least one bound excited state with binding energy of 0.864 ± 0.024 eV relative to the ground state of the europium atom. The experimental results are consistent with recent EA measurements of lanthanide atoms whose anions are predicted to have [Xe](4f<sup>n</sup> 6p) (where n is odd) configurations. |
