We found geomagnetic conjunction events of DE-1 and DMSP in which these satellites respectively observed Pc5 pulsations and particle precipitation approximately on the same geomagnetic field lines. The invariant latitude ranges for the observations of Pc5 and precipitation of 3 keV electrons were almost the same. A statistical study also showed that the region of the central plasma sheet obtained by P. T. NEWELL and C.-I. MENG (J. Geophys. Res., 99,273,1994) falls in the region of the occurrence of transverse Pc5 pulsations. The precipitation of electrons having energies greater than 3 keV was investigated. It is shown that there are differences in the characteristics of 30 keV electron precipitation between the cases in which pulsations were observed and those in which pulsations were not observed. These results suggest that electrons are modulated by transverse Pc5 pulsations.}, pages = {34--41}, title = {Particle precipitation associated with transverse Pc5 pulsations}, volume = {9}, year = {1996} }
