Abstract
The authors have calculated the total dielectronic recombination rate coefficient alpha d(i; tot) for the ground level of sixteen Be-like ions ranging from C2+ to Mo38+. They express alpha d (2 1S-2wP) in LS coupling allowing for configuration mixing in the initial and final states. The author then uses intermediate coupling core excitation energies (w=1 and 3) and core radiative rates (w=1) in the calculation of alpha d. They also allow for the radiative stabilisation of the spectator electron. They calculate alpha d(2-3) in multiconfiguration LS coupling and intermediate coupling using AUTOSTRUCTURE, as described in an earlier paper, allowing for Delta nc=0 and Delta nc0 secondary autoionisation. The authors present tables of results for each core contribution to alpha d(i; tot) over a wide range of temperatures for each ion. Comparison is made with the results of other workers where possible.
