Finite field calculations of static polarizabilities and hyperpolarizabilities of In${}^{+}$ and Sr

Abstract

The finite field calculations are performed for two heavy frequency-standard candidates In${}^{+}$ and Sr. The progressive hierarchy of electron correlations is implemented by the relativistic coupled-cluster and configuration interaction methods combined with basis set of increasing size. The dipole polarizabilities, dipole hyperpolarizabilities, quadrupole moments, and quadrupole polarizabilities are recommended for the ground state 5s${}^2$ ${}^1{S}_0$ and low-lying states 5s5p ${}^3{P}_{0,1,2}^{\mathrm{o}}$ of In${}^{+}$ and Sr. Comparative study of the fully and scalar relativistic electron correlation calculations reveals the effect of the spin-orbit interaction on the dipole polarizabilities of In${}^{+}$ and Sr. Finally, the blackbody-radiation shifts due to the dipole polarizability, dipole hyperpolarizability, and quadrupole polarizability are evaluated for the clock transition 5s${}^2$ ${}^1{S}_0$ - 5s5p ${}^3{P}_0^{\mathrm{o}}$ of In${}^{+}$ and Sr.
