  A heliopause spectrum at 122 AU from the Sun is presented for galactic
electrons over an energy range from 1 MeV to 50 GeV that can be considered the
lowest possible local interstellar spectrum (LIS). The focus is on the spectral
shape of the LIS below 1.0 GeV. The study is done by using a comprehensive
numerical model for solar modulation in comparison with Voyager 1 observations
at 110 AU from the Sun and PAMELA data at Earth. Below 1.0 GeV, this LIS
exhibits a power law,E to the power -(1.55+-0.05), where E is the kinetic
energy. However, reproducing the PAMELA electron spectrum averaged for 2009,
requires a LIS with a different power law of the form E to the power
-(3.15+-0.05) above about 5 GeV. Combining the two power laws with a smooth
transition from low to high energies yields a LIS over the full energy range
that is relevant and applicable to the modulation of cosmic ray electrons in
the heliosphere. The break occurs between 800 MeV and 2 GeV as a characteristic
feature of this LIS.
