Intensity of hydrogen lines in the spectra of moving media. II

Sobolev's theory for media with line self-absorption (e.g., Seyfert galaxies) is used to calculate the intensities of hydrogen lines, assuming the stationary population of hydrogen-atom levels to be sustained by radiative and collisional mechanisms of heating and ionization. The central radiation source is characterized by a nonthermal spectrum F_nu = F_0(nu/nu sub 0) exp -alpha, where alpha = 1, F₀ = 1000 erg/sq cm s Hz for nu₀ = 6.2 x 10 to the 14th Hz. The quantum yield from the medium is determined by the presence of a velocity gradient equal to 5 x 10 to the -11th/s. The F₀ flux impinges on the internal boundary of the shell situated 10 to the 17th cm from the galactic center. I(ji)/I(Lyman-alpha) ratios are presented in tabular form for electron temperatures of (1-2.5) x 10 to the 4th K and electron densities of 10-billion to one-trillion per cu cm.
