Abstract

Precise spectra of electron and positron fluxes in energy range from 80 MeV to several GeV below the geomagnetic cutoff rigidity were obtained using data of the PAMELA magnetic spectrometer. It was launched on June 15th 2006 onboard the Resurs-DK satellite on an elliptical orbit (the inclination is 70, the altitude is 350-610km). The work presents measurements of spatial distributions of secondaries produced in interactions of cosmic ray protons with the residual atmosphere in the near Earth space. Altitude , latitudinal and longitudinal dependences are discussed. These results are particularly interesting for more accurate definition of flux model in the Earth magnetosphere.
