The thermodynamics of monoatomic gas (helium) adsorbed on one-dimensional groove positions on carbon nanolube bundles has been investigated theoretically. The model of lattice gas type is based on account of equilibrium conditions between two subsystems: quasi-one-dimensional helium in grooves and three-dimensional helium atmosphere closed within the free volume of an experimental cell (the total amount of helium atoms in the system is taken to be constant). The analytical calculations of the energy and the heat of adsorption have been compared with the experimental data.1
