DR resonance structure for neon-like ions Al3+,
Ar8+, and Fe16+ forming sodium-like ions. The theoretical results have been
convolved with a simulated experimental energy spread represented by a
flattened Maxwellian with

Figure 2: Maxwellian-averaged DR and RR rate coefficients for recombination of Ar8+ to Ar7+. Present results for DR (thick solid curve) and RR (thin solid curve) were obtained in the MCBP calculations with the code AUTOSTRUCTURE. Also shown are the MCDF results of Chen (1986, solid circles), which were used for the compiled data of Mazzotta et al. (1998, dotted curve), the FAC results of Gu (2003b, dash-dot-dotted curve), the results of Romanik (1988, dashed curve), and the results of Fournier et al. (1997, solid squares) using the fully relativistic, parametric potential atomic structure code RELAC. |

Figure 5: Maximum total DR rate coefficients as a function of atomic number Z. The open circles represent our MCBP calculations. Comparison is given with the calculations of Jacobs et al. (1977, 1979, open squares), the Hartree-Fock distorted-wave calculation of Roszman (1979, open diamond), the MCDF calculations of Chen (1986, crosses), the compilation data of Mazzotta et al. (1998, solid squares), and with the relativistic DW calculations of Fournier et al. (1997, solid up triangles) and Gu (2003a, solid down triangles; 2003b, open down triangles . Lines are drawn through our data and those of Mazzotta et al. to guide the eye. |
