We present the first direct observation of temperature-dependent Fermi wave vectors in the quasi-one-dimensional conductor K0 3MoO3. By monitoring the position of these vectors through the Peierls transition using angle-resolved photoemission spcctroscopy. we demonstrate that the temperature dependence of the charge-density-wave vector observed in earlier experiments is actually that of the Fermi wave vectors.
