Charge Transfer Between Neutral Atoms and Highly Ionized Species: Implications for ISO Observations
G. J. Ferland, K. T. Korista, D. A. Verner +1
We estimate rate coefficients for charge transfer between neutral hydrogen and helium and moderate to highly ionized heavy elements. Although charge transfer does not have much inf…
Comment on a paper by M. A. Bautista ``Atomic data from the Iron Project. XVI. Photoionization cross sections and oscillator strengths for Fe V''
D. A. Verner, D. G. Yakovlev, I. M. Band +1
Recently, Bautista (1996, A&AS, 119, 105) reported new calculations of photoionization cross sections for Fe V, and compared them with the earlier results of Reilman & Manson (1979…
Physical Conditions in Low Ionization Regions of the Orion Nebula
J. A. Baldwin, A. Crotts, R. J. Dufour +12
We reexamine the spectroscopic underpinnings of recent suggestions that [O I] and [Fe II] lines from the Orion H II region are produced in gas where the iron-carrying grains have b…
Atomic Data for Permitted Resonance Lines of Atoms and Ions from H to Si, and S, Ar, Ca and Fe
D. A. Verner, E. M. Verner, G. J. Ferland
We list vacuum wavelengths, energy levels, statistical weights, transition probabilities and oscillator strengths for permitted resonance spectral lines of all ions of 18 astrophys…
Atomic Data for Astrophysics. II. New Analytic Fits for Photoionization Cross Sections of Atoms and Ions
D. A. Verner, G. J. Ferland, K. T. Korista +1
We present a complete set of analytic fits to the non-relativistic photoionization cross sections for the ground states of atoms and ions of elements from H through Si, and S, Ar,…
Atomic data for astrophysics. I. Radiative recombination rates for H-like, He-like, Li-like and Na-like ions over a broad range of temperature
D. A. Verner, G. J. Ferland
We present new calculations and analytic fits to the rates of radiative recombination towards H-like, He-like, Li-like and Na-like ions of all elements from H through Zn (Z=30). Th…
