Abstract
The linewidth for electronic transitions in the image-induced potential well at the surface of liquid helium with a magnetic field applied parallel to the surface is observed to decrease as electron areal density increases. The interpretation is that the lines are motionally narrowed. The electron-velocity autocorrelation time is deduced from the data.Keywords
