We measured the absorption of the energy of an electromagnetic field by surface electrons in the temperature interval 0.48-1.9°K at 2.98 and 14.65 MHz. The measurements have made it possible to determine the mobility of the surface electrons. It was observed that at T< ΓΚ the presence of the surface exerts a substantial influence on the character of the electron motion.
