  Thermonuclear fusion reaction rates in the solar plasma are enhanced by the
presence of the electron cloud that screens fusing nuclei. The present work
studies the influence of electron screening deformations on solar reaction
rates in the framework of the Debye-Huckel model. These electron-ion cloud
deformations, assumed here to be static and axially symmetric, are shown to be
able to considerably influence the solar neutrino fluxes of the pp and the CNO
chains, with reasonable changes in the macroscopic parameters of the standard
solar model (SSM) . Various known deformation sources are discussed but none of
them is found strong enough to have a significant impact on the SSM neutrino
fluxes.
