• A new experimental method has been developed for studying coupled plasmon-rip-plon resonances of electron crystal formed on the surface of liquid helium. Measurements are done at temperatures between 0.45 and 0.9 K and electron areal densitiesfrom 5 X 10' to 1.2 X 10' cm '. Resonance frequencies are quantitatively comparedwith the theory by Fisher, Halperin, and Platzman (FHP) and by Namaizawa. Theagreement between the experiment and the FHP theory is satisfactory at low electrondensities, although at high densities a modification is needed. The Debye-Waller facfor of the Wigner crystal is well explained by the Debye model, and the factor isfound to have a significant contribution from the zero-point vibration of the Wignercrystal.
