Query: 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 towards H-like, He-like, Li-like and Na-like ions of all elements
from H through Zn (Z=30). The fits are valid over a wide range of temperature,
from 3 K to 10**9 K.
