Abstract	This is a confirmatory resubmission of the successful AO7 proposal 0720003, currently being carried out, requesting a completion of the programme as described in the original proposal. Recently, significant advances have been made in understanding of the diffuse Galactic continuum emission observed by SPI on INTEGRAL. The hard power-law component has been identified with inverse-Compton emission from relativistic (GeV) electrons on the cosmic microwave background and Galactic infrared radiation field. The observed intensity is in good agreement with detailed predictions from the GALPROP model, which accounts for both primary and secondary electrons and positrons. We propose to exploit this with INTEGRAL to obtain a probe of the distribution of cosmic-ray electrons in the Galaxy, in particular in the Galactic halo seen at high latitudes. To this end we propose a multi-year scan covering a wide latitude range in the inner Galaxy, significantly deepening the exposure over what is currently available. The decreasing background due to the solar cycle will improve the signal-to-noise over that for the INTEGRAL mission so far. The results will have implications for Fermi-LAT which is now in operation - taken together the data from the two missions will constrain the cosmic-ray electron spectrum at GeV energies and help to give an unambiguous decomposition of the diffuse gamma-ray sky.

Mission Description	The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
