✦ Synopsis

Measurements of the longitudinal magnetoconductivity a== of the nondegenerate two-dimensional system of electrons on the surface of liquid helium are presented for magnetic fields up to 22 T in the temperature range 0.4 K < T < 2.1 K. For temperatures above 1.6 K our experimental results axe in good agreement with a quantum magnetotransport theory of short-range scattering within broadened Landau levels. If the temperature is reduced below 1.5 K, a deviation of the experimental data from the theoretical calculations is observed for magnetic fields between 2 T and 10 T. At temperatures T < 0.8 K where the conductivity of the surface electrons is determined by the scattering between electrons and ripplons, the magnetic field dependence of our measurements of 1/a==(B) for high fields is rather poorly reproduced by the existing theories.
