The charge-density wave (CDW) structure in NbSe/sub 3/ due to the two independent CDW's has been imaged by scanning microscopy. As predicted by band-structure considerations, the CDW modulation is observed to be substantially localized on different chains for the separate CDW's. AT 77 K where only the high-temperature CDW exists, a relatively weak modulation with a single component along the b axis is observed. At 4.2 K the low-temperature CDW contributes a much stronger approx.4b/sub 0/ x 2c/sub 0/ superlattice modulation.
