A novel neutron scattering technique has been utilized to discover one-dimensional fluctuations with a very sharply defined modulation period of 16.65 A along the {ital b}({ital a}) direction in YBa{sub 2}Cu{sub 3}O{sub 6.93}. The fluctuations are found to be absent in the reduced oxygen compound YBa{sub 2}Cu{sub 3}O{sub 6.15}. The wave vector of the fluctuations is consistent with accepted values of 2{ital k}{sub {ital F}} for the Cu-O chains. {copyright} {ital 1996 The American Physical Society.}
