Abstract

The secondary e+ and e- populations in near earth's orbit have been calculated by simulation. The results are in very good agreement with the recent AMS measurements. The e⁺ over e^- flux ratio for particles below the geomagnetic cutoff appears to be due to the geomagnetic East-West effect.
