Critically evaluated theoretical energies, lifetimes, static and dynamic polarizabilities, and magic wavelengths in cesium

Systematic study of Cs atomic properties is carried out using a high-precision relativistic all-order method. Excitation energies of the $ns$, $np$, $nd$, and $nf$ (n $\leq$ 12) states in neutral cesium are evaluated. Reduced matrix elements, transition rates, and lifetimes are determined for the levels up to $n$ = 8. Recommended values and estimates of their uncertainties are provided for a large number of electric-dipole transitions. Electric-dipole ($6s-np$, $n$ = 6-26)and electric-quadrupole ($6s-ndj$ , $n$ = 5-26) matrix elements are calculated to obtain the ground state E1 and E2 static polarizabilities. Scalar polarizabilities of the $ns, np, and nd$ states, and tensor polarizabilities of the $np_{3/2}$ and $nd_j$ excited states of Cs are evaluated. These calculations provide recommended values critically evaluated for their accuracy for a number of Cs atomic properties useful for a variety of applications. Using first-principles calculations, we identify magic wavelengths $\lambda$ for the $6s-7p_{1/2}$ and $6s-7p_{3/2}$ transitions in Cs. The $ns$ and $np_j$ atomic levels have the same ac Stark shifts at the corresponding magic wavelength, which facilitates state-insensitive optical cooling and trapping.
