Phys. Rev. Lett. 91, 076104 (2003) [4 pages]Observation of Heterodyne Mixing in Surface X-Ray Photon Correlation Spectroscopy ExperimentsSee Also: Erratum Received 4 February 2003; published 15 August 2003 We report measurements of propagating capillary waves on a liquid water surface at T=5 °C with x-ray photon correlation spectroscopy. The experiment has been performed under grazing incidence conditions with an incoming x-ray beam below the critical angle of total external reflection. In the q region investigated the measured intensity-intensity autocorrelation functions of the liquid water surface were found to be heterodyne signals, i.e., a combination of first- and second-order correlation functions g1(τ) and g2(τ). © 2003 The American Physical Society URL:
