Long-range interactions of the Sr+ ion

James Mitroy, J Zhang, Michael Bromley

    Research output: Contribution to journalArticlepeer-review


    A number of properties of the low-lying states of the Sr+ ion are evaluated by diagonalizing a semiempirical Hamiltonian in a large dimension single electron basis. These properties include the oscillator strengths connecting the low-lying states, the quadrupole moments, and the polarizabilities. In addition, the long-range dispersion coefficients for the states of this ion interacting with a number of atoms are given. The polarizabilities and dispersion coefficients can be used to estimate frequency shifts of the Sr+ 5s?4d clock transition due to background fields, including the blackbody radiation shift, and shifts due to collisions with a buffer gas. � 2008 The American Physical Society.
