Abstract
The dynamic polarizabilities of the atomic states with angular momentum are sensitive to the angle between the quantization axis and the polarization vector owing to the contribution of anisotropic tensor polarizabilities. The magic wavelength at which the differential Stark shift of an atomic transition nullifies depends on this angle. We identified the magic wavelengths for the transitions of ions at different angles between and in the case of linearly polarized light. The magic wavelengths near 395.79 nm, which lie between the and transition wavelengths, remain insensitive to the angle, while the longest magic wavelength, which is around 1000 nm, for each of the magnetic sublevel transitions is very sensitive to the angle. We suggest that accurate measurements on the longest magic wavelengths for the and transitions can be used to determine the oscillator strengths for the , and transitions, and the difference of the static polarizabilities of the and states, and the tensor polarizability of the state.
