Phys. Rev. B 66, 205406 (2002) [6 pages]Adsorption of He atoms in external grooves of single-wall carbon nanotube bundlesReceived 28 June 2002; published 14 November 2002 I calculate the quantum states for He atom in the potential of an external groove of the single-wall carbon nanotube bundle. The calculated ground-state energy is found to be in fair agreement with the experimental estimate which suggests that the outer groove site is a preferential site for the adsorption of He gas in the samples studied experimentally. I also calculate the specific heat of low-density 4He atom gas adsorbed in groove positions. The specific geometry of the groove and its influence on the adsorbate quantum states and specific heat are discussed. © 2002 The American Physical Society URL:
