J/A+A/526/A115 Electron-impact excitation of H-like ions (Malespin+, 2011) ================================================================================ Electron-impact excitation of H-like Cr, Mn, Fe, Co and Ni for applications in modeling X-ray astrophysical sources.

We calculate high quality electron-impact excitation collision strengths and effective collision strengths for hydrogenic Cr, Mn, Fe, Co, and Ni. We use the Dirac R-matrix method, the intermediate coupling frame transformation R-matrix method, the semi-relativistic distorted-wave method and the fully-relativistic distorted-wave method to calculate collision strengths for each of the ions. The ADAS collisional-radiative codes are used to produce photon emissivity coefficients for each ion. Description: These tables contain level energies, spontaneous emission coefficients and effective collision strengths for H-like Mn, Cr, Fe, Co and Ni. The data is for the first 5 n-shells. The atomic data is for use in modelling emission from supernovae remnant plasmas, or other highly charged astrophysical sources. A second set of atomic data is also archived, containing the photon emissivity coefficients for the strongest transitions for each of these ions, on a temperature/density grid. The files in ADAS format are available in adas subdirectory. There are two types of data we made, one containing the description of the ion and the effective collision strengths and spontaneous emission coefficients. The other file contains the photon emissivities on a temperature/density grid of values. ADAS provides fortran routines which can read these files File Summary: -------------------------------------------------------------------------------- FileName Lrecl Records Explanations -------------------------------------------------------------------------------- ReadMe 80 .
