  We discovered that spin-orbit scattering in strong-disordered gold
nanojunctions is strongly suppressed relative to that in weak-disordered gold
thin films. This property is unusual because in weak-disordered films,
spin-orbit scattering increases with disorder. Granularity and freezing of
spin-orbit scattering inside the grains explains the suppression of spin-orbit
scattering. We propose a generalized Elliot-Yafet relation that applies to
strong-disordered granular regime.
