Abstract

Strong evidence against stability of the negative ion of ytterbium is presented, and the prediction is made that the lowest negative ion state Yb⁻4f¹⁴6s²6p ²P_1/2 is a narrow shape resonance in the electron–atom continuum at 20 meV. These results are obtained from the many-body theory calculations with the electron–atom correlation potential appropriately scaled to reproduce the experimental data for the isoelectronic neutral Lu and Ba⁻. They are in agreement with the recent thorough experimental investigation of Yb⁻ by the Aarhus group.
