Comparative studies of dipole polarizabilities in Sr${}^{+}$, Ba${}^{+}$ and Ra${}^{+}$ and their applications to optical clocks

B. K. Sahoo, R. G. E. Timmermans, B. P. Das +1

Static dipole polarizabilities are calculated in the ground and metastable states of Sr${}^{+}$, Ba${}^{+}$ and Ra${}^{+}$ using the relativistic coupled-cluster method. Trends of the electron…
