Abstract
An analysis of x-ray data from vanadium-doped blue bronze K 0.3(Mo $_{\rm 1-x}$V $_{\rm x}$)O 3 is presented for x=2.8% and 1.44%. 2k $_{\rm F}$ satellite reflections are broadened in all the directions and exhibit a peculiar profile asymmetry in the chain direction We interpret this profile asymmetry by the presence of Friedel oscillations around the charged vanadium impurities.
