Steady-state multipole moments of atoms ρK q of the rank K ≤ 2 are analytically calculated for all closed dipole transitions Jg → Je in a resonant radiation field with arbitrary intensity and arbitrary elliptical polarization. The nonlinear propagation of a monochromatic elliptically polarized wave through a medium consisting of atoms with resonant transition Jg → Je is considered as an application.

We present a complete set of analytical and invariant expressions for the steady-state density matrix of atoms in a resonant radiation field with arbitrary intensity and polarization. The field drives the closed dipole transition with arbitrary values of the angular momenta ${J}_{g}$ and ${J}_{e}$ of the ground and excited state. The steady-state density matrix is expressed in terms of spherical harmonics of a complex direction given by the field polarization vector. The generalization to the case of broadband radiation is given. We indicate various applications of these results.

We present analytical and invariant expressions for the steady-state density matrix of atoms in a resonant radiation field with arbitrary intensity and arbitrary elliptical polarization. The field drives the closed dipole transition with arbitrary values of the angular momenta of the ground Jg and excited Je states. These transitions can be classified depending on the structure of the solution and its physical peculiarities.
