Rayleigh scattering for photon energies close to core-core transitions resonances in highly charged lead ions is investigated theoretically. Angular distribution of cross section and polarization of the scattered light is obtained using rigorous quantum electrodynamics approach. The results are compared to those given by often used simple dipole approximation. It is shown that for certain scenarios a significant effect of higher multipoles on both angle-differential cross section and linear polarization of the scattered light can be indicated.
