Rate coefficients for collisional-radiative recombination (CRR) of Ar{sup +} ions with electrons have been measured at temperatures from 77 to 180 K in a helium-buffered flowing-afterglow (Cryo-FALP) experiment at electron densities n{sub e} from 10{sup 8} to 10{sup 10} cm{sup -3}. The measured ternary rate coefficient K{sub CRR} at 77 K is (1.1{+-}0.4)x10{sup -17} cm{sup 6}s{sup -1} and the observed variation with temperature agrees well with the theoretical T{sup -4.5} dependence.
