Description

The important electron quadrupole 1D-1S transition probabilities for Be, Mg and Ca have been computed using a fully relativistic multiconfiguration Dirac-Fock method with Breit and QED corrections. In Coulomb gauge, the authors' computed Einstein coefficient for Ca of 48.1s-1 is in good agreement with the recent experimental value of 40 +- 8s-1. The authors' best Einstein coefficients for Be and Mg are 3884.9s-1 and 2357.2s-1, respectively. The existing discrepancy between theory and experiment in Ca is eliminated. There are no previous results for Be and Mg
