Abstract

New observations of the quiet-time energy spectrum of 0.16 to 3 MeV electrons have been made with teh Caltech Electron/Isotope Spetrometer which was launched on IMP-7 in September 1972. Recent measurements of quiet-time electrons in this energy range by other groups have resulted in spectra differing by more than an order of magnitude in intensity. We find a minimum quiet-time flux level similar to the lowest previously reported spectra and consistent with an extrapolation of the spectrum measured at higher energies. A galactic secondary source of knock-on electrons is consistent with our results provided there is negligible solar modulation. Although not required, other recently suggested sources may also contribute to the observed fluxes.
