combination coefficient

A measure of the specific rate of disappearance of small ions due to either 1) union with neutral Aitken nuclei to form new large ions; or 2) union with large ions of opposite sign to form neutral Aitken nuclei. Dimensionally, a combination coefficient is identical with the physically similar recombination coefficient. Both types of combination coefficients exhibit mean values of the order of 10āˆ’5cm3sāˆ’1 at sea level, while the recombination coefficients are typically about one order of magnitude smaller. See recombination, small-ion combination.
