Abstract : The clustering of Ar to Li(+) has been studied experimentally using a drift tube. Under reported conditions, the major reaction is Li(+) + Ar + Ar = Li(+)(Ar) + Ar . The rate coefficients and the mobility of Li(+)(Ar) were deduced by comparing measured arrival time profiles of the ions with profiles generated by a three-dimensional, numerical drift tube model. The predictions of this model are compared in some detail with those of two analytical, three-dimensional, drift-tube models. The mobilities of K(+) in N2 and of K(+) in Ar were determined during checks for systematic errors in the new drift tube. The mobility of Li(+) in Ar was also determined in the course of this work.
