In the paper [3], J. Franks and RF Williams gave the first examples of nontransitive Anosov flows, that is, Anosov flows [1]< j) t: M'-> M for which the nonwandering set Gl (< f> t) is different from all of M. They showed that such examples can exist even in the smallest dimension, dimM= 3. If (j> t is a nontransitive Anosov flow on M, then Q (0e) admits a spectral decomposition [12, 11]: Cl (< pt)={JfLiQ, where each Q;(called a basic set) is closed,^-invariant and transitive, and Qjf] Q, k= 0 for all j# k. In this note we show that the basic sets of a nontransitive Anosov flow in dimension 3 can be separated by incompressible and pairwise nonisotopic tori.
