Popis:	The cross section for single-photon detachment of an electron from the metastable ${\mathrm{Be}}^{\mathrm{\ensuremath{-}}}$ ion has been measured at a photon energy of 2.076 eV to be 31\ifmmode\pm\else\textpm\fi{}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 \ensuremath{\beta}=0.49\ifmmode\pm\else\textpm\fi{}0.02 at the same energy.
