摘要：

The electron affinity of atomic iodine has been determined to be 3.059 038(10) eV. A beam of negatively charged iodine ions was merged collinearly with a laser beam. The onset of the photodetachment process was observed when the wavelength of the laser was scanned, and the result was fitted according to the Wigner law in order to determine the photodetachment threshold. The wavelength was calibrated by simultaneously recording the atomic spectra of lead and manganese as well as the fringes from a Fabry-Perot reference etalon.
