Abstract

The existence of the theoretically predicted

2 s 2 p^{2} {}^{4}P^{e}

metastable

{Be}^{-}

ion has been confirmed by experiment. The autodetachment decay rates at several decay times after formation show the presence of more than one substate, with the lifetime of the longest component exceeding 100 μs.
