    This review covers recent achievements in the studies of quantum properties of the novel carbon materials (fullerite C₆₀ and bundles of single-walled nanotubes (SWNT)) saturated with such light-mass species as helium ...
  • Strzhemechny, M.A.; Legchenkova, I.V. (Физика низких температур, 2010)
    A model for an atomic impurity in an octahedral void of fullerite C₆₀ is suggested. The problem is solved in the spherical oscillator approximation, which is appropriate for the larger rare gas atoms. It is shown that such ...
