摘      要：By using the multichannel quantum defect theory （MQDT）, we have evaluated the energy levels and lifetimes of 2sns （）3S1,2snd（）3D（n=3-25） of BeⅠ and 1sns（）3S1,1snd （）3D（n=3-25） of BeⅢ. These energies and lifetimes that we have calculated not only agree with the recent measurements and theoretical calculation of Ref.4 and Ref.3, but also predict the lifetimes of 66 other highly excited states.
