Strong evidence against stability of the negative ion of ytterbium is presented, and the prediction is made that the lowest negative ion state Yb4f146s26p 2P1/2 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.
