The cross section for single-photon detachment of an electron from the metastable Be[sup [minus]] ion has been measured at a photon energy of 2.076 eV to be 31[plus minus]3 Mb. The method of laser photodetached electron spectroscopy was used in the measurement and the asymmetry parameter that characterizes the angular distribution of the detached photoelectrons was also measured to be [beta]=0.49[plus minus]0.02 at the same energy.
