An analytical and invariant expression is given for the steady-state density matrix of free atoms in a monochromatic radiation field with arbitrary intensity and arbitrary elliptical polarization. The field drives the closed transition , with arbitrary values of F. This is the only class of transitions where a closed analytical expression for the steady state was lacking. Some applications of this result are indicated.
