Abstract
A novel neutron scattering technique has been utilized to discover one -dimensional fluctuations with a very sharply defined modulation perio d of 16.65 Angstrom along the b(a) direction in YBa2Cu3O6.93. The fluc tuations are found to be absent in the reduced oxygen compound YBa2Cu3 O6.15. The wave vector of the fluctuations is consistent with accepted values of 2kF for the Cu-O chains.
