Relativistic many-body calculations of energy levels, hyperfine constants, electric-dipole matrix elements, and static polarizabilities for alkali-metal atoms
Relativistic many-body calculations of energy levels, hyperfine constants, electric-dipole matrix elements, and static polarizabilities for alkali-metal atoms
Removal energies and hyperfine constants of the lowest four $ns,$ ${\mathrm{np}}_{1/2},$ and ${\mathrm{np}}_{3/2}$ states in Na, K, Rb, and Cs are calculated; removal energies of the $n=7--10$ states and hyperfine constants of the $n=7$ and 8 states in Fr are also calculated. The calculations are based on the relativistic single-double …
