    "abstract": "Our numerical calculations on small carbon clusters point to the existence of\na metastable three-dimensional eight-atom cluster C$_8$ which has a shape of a\nsix-atom triangular prism with two excess atoms above and below its bases. We\ngave this cluster the name \"prismane\". The binding energy of the prismane\nequals to 5.1 eV/atom, i.e., is 0.45 eV/atom lower than the binding energy of\nthe stable one-dimensional eight-atom cluster and 2.3 eV/atom lower than the\nbinding energy of the bulk graphite or diamond. Molecular dynamics simulations\ngive evidence for a rather high stability of the prismane, the activation\nenergy for a prismane decay being about 0.8 eV. The prismane lifetime increases\nrapidly as the temperature decreases indicating a possibility of experimental\nobservation of this cluster.",
