Abstract
We have calculated total and final-state resolved partial dielectronic recombination (DR) rate coefficients for 32 H-like ions: He + through Zn 29+ plus Kr 35+ ,M o 41+ and Xe 53+ . Breit–Pauli intermediate coupling calculations have been carried-out which allow for l-mixing within the He-like autoionizing complex. We discuss the comparison of these results with those of other workers, and with experiment. Fitting coefficients which describe the total DR rate coefficients are presented in this paper. A full set of partial results can be accessed from the Atomic Data and Analysis Structure (ADAS) database or from the Oak Ridge Controlled Fusion Atomic Data Center under http://www-cfadc.phy.ornl.gov/data_and_codes.
