The quantum interference (QI) of charge carriers in a magnetic field is obtained in the organic conductor (Per)(2)Au(mnt)(2) by suppressing the charge-density-wave (CDW) state with pressure. The QI oscillation amplitude exhibits a temperature-dependent scattering rate, indicative of an inhomogeneous metal-CDW ground state. The QI oscillation frequency reveals a Fermi-surface topology in close agreement with band-structure predictions. The value of the frequency is quite small, making the limit of constructive interference experimentally accessible.
