Phys. Rev. A 70, 052503 (2004) [8 pages]Properties of the triplet metastable states of the alkaline-earth-metal atomsReceived 25 April 2004; published 11 November 2004 The static and dynamic properties of the alkaline-earth-metal atoms in their metastable state are computed in a configuration interaction approach with a semiempirical model potential for the core. Among the properties determined are the scalar and tensor polarizabilities, the quadrupole moment, some of the oscillator strengths, and the dispersion coefficients of the van der Waals interaction. A simple method for including the effect of the core on the dispersion parameters is described. © 2004 The American Physical Society URL:
