    Abstract

    The polarizabilities of the three lowest states of the beryllium atom are determined from a large basis configuration interaction calculation. The polarizabilities of the 2s2 1Se ground state (37.73a30) and the 2s2p 3Po0 metastable state (39.04a30) are found to be very similar in size and magnitude. This leads to an anomalously small blackbody radiation shift at 300 K of −0.018(4) Hz for the 2s2 1Se–2s2p 3Po0 clock transition. Magic wavelengths for simultaneous trapping of the ground and metastable states are also computed.
