Z-SCALED DATA FOR DIELECTRONIC RECOMBINATION FROM O-LIKE TO F-LIKE IONS

Dielectronic-recombination (DR) data such as singly and doubly excited -state energies, autoionization rates to ground and excited states, ra diative decay rates to singly excited states, and DR branching ratios are presented for recombination from oxygen-like to fluorine-like Ar, Ti, Fe, and Se ions. These data have been obtained using a detailed Ha rtree-Fock calculation with relativistic corrections. Three- and four- parameter fits to these data were then made to obtain scaling relation s for the above mentioned quantities. Using these scaling relations on e can thus interpolate the DR data for any ion with atomic number 18 l ess-than-or-equal-to Z less-than-or-equal-to 34. By extrapolation, one should also be able to calculate the DR data to atomic numbers in som e range beyond Z = 34. (C) 1994 Academic Press, Inc.
