摘要: The polarizabilities of the low lying states Mg+ and Ca+ ions are evaluated by diagonalizing semi-empirical Hamiltonians in a large dimension single electron basis. quadrupole moment metastable 3d state is also calculated within 1% recent experimental value while being 5% smaller than some ab-initio calculations. In addition, long range dispersion coefficients for these interacting with number atoms given. Oscillator strengths given generally agree most sophisticated can be used to estimate frequency shifts 4s ↦ clock transition due background electric fields collisions buffer gas.
