We have found a first order phase transition separating a low-density liquid phase in which all He4 atoms are adsorbed close to the tube wall and a high-density arrangement characterized by two helium concentric layers. The energy correction due to the presence of neighboring tubes in a bundle has also been calculated, finding it negligible in the density range considered.application/pdfenAmerican Physical SocietyAdsorptionNanotubesjournal articleopen access
