We have determined the interstellar spectra of cosmic ray protons andelectrons from a few MeV to ~10 GeV. These interstellar spectra are based onVoyager data and a normalization of specific galactic propagation modelcalculations of both protons and electrons to PAMELA data at the Earth at 10GeV, where the solar modulation is small. These resulting interstellar spectraare then compared with spectra of protons and electrons measured at lowerenergies at the Earth by PAMELA in 2009. The total amount of modulation atlower rigidities (energies) is found to be nearly the same at the same rigidityfor both protons and electrons and ranges in magnitude from a factor ~400 at0.1 GV for electrons, to a factor ~15 at 0.44 GV (100 MeV for protons), to afactor ~3.3 at 1 GV for both components. The magnitude of this total modulationof both components are the same to within + 10% from ~0.3 to ~3 GV in rigidity.The observed total modulation for protons can be matched quite closely using asimple spherically symmetric modulation picture involving a force field modelfor the modulation and a constant energy loss at all energies. The electronsrequire a set of parameters to calculate more detailed features of themodulation using the diffusion coefficient and its variation with rigidity andradius at rigidities less than few GV.
