## Polarized line formation by resonance scattering## II. Conservative case
We consider multiple resonance scattering with complete frequency
redistribution (CFR) in a semi-infinite conservative atmosphere
(photon destruction probability with the sources
at infinite depth. The polarization arising in resonance scattering is
completely accounted for. The problem we consider is the
resonance-scattering counterpart of the Chandrasekhar-Sobolev problem
of Rayleigh scattering in the conservative atmosphere. The numerical
data on the matrix source function in the
atmosphere with conservative dipole resonance scattering (the
depolarization parameter ) are presented; we
assume Doppler profile. The source matrix is found by a non-iterative
numerical solution of the matrix Wiener-Hopf integral equation with
the matrix -operator. Depth dependence of the
elements of the source matrix is discussed. Some
unexpected peculiarities are revealed in the behavior of its
polarization terms. The matrix which is the
generalization of the Chandrasekhar
