Atomic data for astrophysics. I. Radiative recombination rates for H-like, He-like, Li-like, and Na-like ions over a broad range of temperature

We present new calculations and analytic fits to the rates of radiative recombination toward H-like, He-like, Li-like, and Na-like ions of all elements from H through Zn ({ital Z}=30). The fits are valid over a wide range of temperature, from 3 K to 10{sup 9} K. {copyright} {ital 1996 The American Astronomical Society.}
