Abstract
The positions and line widths of the phonon-ripplon resonances have be en measured in Wigner crystal localized over superfluid helium surface at electron density 1.3 . 10(9) cm(-2) in temperature range 0.08-0.6 K. The positions of the resonances agree with theoretical models avail able at temperatures not far from melting point. The line width decrea ses linearly with lowering temperature.
