The value of the radial gradient of low-energy (˜0.5 2 MeV) protons in the heliosphere at distances of 20 80 AU in the periods of solar activity minima in 1985 1987 and 1994 1997 was estimated using the data of the Voyager-1 and Voyager-2 spacecraft (s/c). Preliminary results on the dependence of the radial gradient on the distance were obtained for protons of these energies. The value of the radial gradient varies from -3% (AU)-1 to -1% (AU)-1 at distances from the Sun of ˜20 60 AU, reaching +0.7% (AU)-1 at maximum considered distances (˜80 AU). The sign reversal of the proton radial gradient at a distance of 60 70 AU is interpreted as the appearance of a new component: up to the point of inversion there are mainly particles of the solar origin and/or accelerated in the inner heliosphere, while after the reversal of the gradient’s sign the fluxes of particles prevail whose source is located far from the Sun (maybe in the vicinity of the heliosphere boundary in the region of existence of the termination shock).
