  Effects of the interchannel coupling on the spin polarization of energetic
photoelectrons emitted from atomic Ne valence subshells are examined. Like
previously obtained results for cross sections and angular distributions, the
photoelectron spin polarization parameters too are found considerably
influenced by the coupling. The result completes a series of studies to finally
conclude that the independent particle description is inadequate for the {\em
entire} range of photoionization dynamics over the {\em full} spectral energy
domain
