Аннотация: 127 one-hour average samples of central plasma sheet ions and electrons were analysed in order to determine spectral characteristics of these magnetotail particle populations during periods of low geomagnetic activity (AE100 nT). Particle data from the low energy proton and electron differential energy analyzer (LEPEDEA) and medium energy particle instrument (MEPI) on ISEE 1 were combined to obtain differential energy spectra in the plasma sheet at geocentric radial distances R12 RE. It was found that, for even the longest periods sampled, the nearly isotopic central plasma sheet total ion and electron populations were measured to be continuous particle distributions from the lowest energy of tens of eV/e to a few hundred keV..
