Density and Ionization Parameters of Line and Continuum Emission from the Outer Regions of Accretion Disk in Active Galactic Nuclei

In this paper, the diffusion source model and the structure of magnetized accretion disk with self-gravity are used to study the density and the ionization parameter of the H_II and H^*₁ zone, of which most likely the broad line emitting region consists. Two different densities and ionization parameters are determined: the first < n( H_II) > and Ξ( H_II) , corresponding to the mean density and ionization parameter in the completely ionized H_II zone, and the second,< n (H^*₁) > and Ξ(H^*₁), to the mean density and ionization parameters in the H^*₁ zone.
