Be - has been predicted to have three bound states of which the 1s2s2p 2 6 S 5 6/ 0 decays to a multichannel continuum via relativistic autoionisation. Application of a state-specific theory of electron correlation, relativistic effects and interchannel coupling has yielded tau =8.3*10 -3 s for the lifetime of this level.
