Abstract
We review recent measurements of cosmic ray electrons and positrons. In contrast to the earlier situation there now appears to be good agreement between different measurements of the electron spectrum at 10 GeV. These measurements are consistent with the previous so called “high” intensities. This new level of agreement permits the interstellar electron spectrum to be derived in a more precise way directly from the radio background measurements. This new electron spectrum is interpreted with regard to its implications for the various energy loss processes occurring in interstellar space and also for its implications regarding the production of gamma-rays below ~ 100 MeV. A primary electron spectrum after accleleration with an index of -2.3 ± 0.1 between a few MeV and several hundred GeV is consistent with the data.
