摘要：

The specific heat C (P) of quasi-one-dimensional Xe adsorbate chains in grooves on the outer surface of closed single-walled carbon nanotube bundles in the temperature interval of 2-55 K has been measured. Experimental data have been compared to the theoretical C (V) values. The sharp increase in the difference C (P) - C (V) above 30 K has been explained within the model of formation of single thermal vacancies in the one-dimensional Xe adsorbate chains. The enthalpy, entropy, and concentration of thermal vacancies have been determined.
