Z-scaled k-shell dielectronic recombination rate coefficients

We present total as well as state-specific dielectronic recombination (DR) data such as singly and doubly-excited state energies, autoionization and radiative rates and DR branching ratios for recombination from H-like to He-like and from He-like to Li-like ions. The data obtained are calculated using a detailed Hartree-Fock calculation with relativistic corrections. Explicit calculations for Al, Ti, and Kr are performed to cover a range of ions such that scaling relations obtained using these data can be used to interpolate the DR data for any ion of interest within this range and may be somewhat beyond. Since accurate and detailed state-specific knowledge of DR rate coefficients are crucial for atomic model development of any species, these present data will be extremely relevant for analysis of z-pinch physics.
