We present new computations of the equilibrium and non-equilibrium cooling efficiencies and ionization states for radiatively cooling gas clouds with temperatures between 108 and 104K. We focus on the behavior for pure radiative cooling with no external sources of heat or photoionization. We include the elements H, He, C, N, O, Ne, Mg, Si, S, and Fe, and present results for heavy element compositions ranging from 10-3 to 2 times the elemental abundances in the Sun.
