- Abstract
High-precision calculations of the [sup 3,1]P[sup 0][sub 1](nsnp)→[sup 1]S[sub 0](ns[sup 2])E1 amplitudes were carried out for magnesium, calcium, and strontium (n = 3, 4, and 5, respectively). The following results were obtained for the reduced matrix element <[sup 1]P[sup 0][sub 1]|| d ||[sup 1]S[sub 0]> of electric dipole moment operator: 4.03(2) au for Mg, 4.91(7) au for Ca, and 5.28(9) au for Sr. These matrix elements are necessary for calculating the van der Waals coefficients C[sub 6], which are used in evaluating the atomic scattering lengths. The latter determine the dynamics and stability of the Bose–Einstein condensate. © 2000 MAIK “Nauka / Interperiodica”.
