Abstract:
We compute the momentum distribution of helium atoms and hydrogen molecules absorbed within an ordered bundle of carbon nanotubes. The results vary significantly as a function of coverage and manifest the strong anisotropy and localization of this geometry. For example, the root-mean-square momentum component perpendicular to the bundle axis can be about three times larger for interstitial molecules than for molecules moving in an axial phase confined by a cylindrical film of particles coating the tube's inner wall. These results (which are consequences of the uncertainty principle) indicate that the momentum distribution is a useful signature of the local geometry and quantum state of the absorbed particles in nanotube bundles.
