The mobilities of He+, He2+, He3+ and He4+ have been measured as a function of E/N at 77K by the Bradbury-Nielsen technique. A second drift tube attached to a quadrupole mass spectrometer was used to assist in ion identification. The equilibrium constants, Ke2,3 Ke3,4 for the reactions He2++He+He to or from He3++He and He3++He+He to or from He4++He respectively have been determined from an analysis of the data. The low-field dependence of the mobility of He+ in He is found to be in good agreement with that predicted from Kihara's theory (1953).
