Abstract

Laser-photoelectron spectroscopy has been used to determine the electron affinity of atomic thallium. Photoelectron kinetic-energy spectra of Tl were obtained and compared to those of Na obtained in the same manner. Using this technique, the electron affinity of thallium was determined to be 0.377±0.013 eV. This value is compared to several recent calculations of the electron affinity of thallium. In addition, a summary of experimental values and several systematic theoretical predictions of the electron affinities of the other group-13 elements is presented.
