Abstract
The electron affinity of lutetium has been measured using laser photodetach ment electron spectroscopy. This is the first electron affinity measurement for lutetium. The electron affinity of lutetium was measured as 0.34 +/- 0 .01 eV. One bound excited state of Lu- was also observed in the photoelectr on spectra, and the binding energy of this excited state relative to the gr ound state of lutetium was measured as 0.16 +/- 0.02 eV. The present experi mental measurements are compared with recent calculations.
