Аннотация

The experimental studies of the heat capacity of 1D chains of xenon atoms adsorbed in the outer grooves of bundles of closed single-walled carbon nanotubes C Xe have been first made at temperature range 2-30 K with the adiabatic calorimeter. The experimental data C Xe have been compared with theory [A. Siber, Phys. Rev. B 66, 235414 (2002)]. The experimental and theoretical heat capacity curves are close below 8 K. Above 8 K the experimental curve C Xe (T) exceeds the theoretical one and excess capacity ΔC Xe (T) increases monotonously with temperature. We assume that the ΔC Xe (T) caused mainly by the increase of the distance between the neighboring xenon atoms in the chain with increasing temperature.
