Solution of the equation of radiative transfer for interlocked doublets by double interval spherical harmonic method

The double-ordinate spherical harmonic method presented by Wilson and Sen (Publ. Astron. Soc. Jpn. 15 (1963) 351) has been used to solve the equation of radiative transfer in the Milne-Eddington model for interlocked doublets. Solutions have been obtained in the first and second approximation in a particular case η1=1; η2=12.
