Abstract: A new method for studying the processes of the establishment of the thermodynamic equilibrium in the adsorbed $^3$He layers in highly porous media has been proposed. Using this method, the thermalization of adsorbed $^3$He on silica aerogel at a temperature of 1.5 K has been studied. The process of the establishment of the thermodynamic equilibrium has been controlled by measuring the pressure in an experimental cell, the amplitude of the NMR signal, and the nuclear spin-spin and spin-lattice relaxation times of adsorbed $^3$He. It has been shown that the establishment of the thermodynamic equilibrium in the adsorbed $^3$He –aerogel system is characterized by a time of 26 min.
