Abstract
We have performed a comparative study of the absolute solar
modulation of cosmic-ray positrons (e^+) and electrons (e^+ + e^-).
We find that the interstellar electron spectrum, which is
described by a power-law slope at higher energies, must flatten
below ~ 100 MeV, that a significant fraction of interstellar
cosmic-ray electrons must originate in "primary" sources, and
that the rigidity dependence of the interplanetary cosmic-ray
diffusion coefficient, R^α, changes from α>O at higher rigidities
to α ≈ -1 below ~ 60 MV.
