Abstract:
Accurate atomic data for the less abundance Fe-peak elements are
required for use in X-ray astrophysical studies.
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
