Abstract: | In this paper we will show that, assuming the existence of a long-range microscopic memory of the random force, acting in
the solar core, mainly on the electrons and the protons rather than on the light and heavy ions (or, equally, assuming the
existence of an anomalous diffusion of solar core constituents of light mass and of normal diffusion of heavy ions), the equilibrium
statistical distribution that these particles must obey, is that of the Tsallis non-extensive statistics, the distribution
differing very slightly from the usual Maxwellian distribution. Due to the high-energy depleted tail of the distribution,
the nuclear rates are reduced and, using earlier results on the standard solar model neutrino fluxes, calculated by Clayton
and collaborators, we can evaluate fluxes in good agreement with the experimental data. While the proton distribution is only
very slightly different from the Maxwell one there is a slightly larger difference with the electron distribution.
