    "abstract": "We present all-electron density functional study of the geometry, electronic\nstructure, vibrational modes, polarizabilities as well as the infrared and\nRaman spectra of fullerene-like arsenic cages. The stability of As$_n$ cages\nfor sizes 4, 8, 20, 28, 32, 36, and 60 wherein each As atom is three-fold\ncoordinated is examined. We find that all the cages studied are vibrationally\nstable and while all the clusters are energetically stable with respect to\nisolated arsenic atoms, only As$_{20}$ is energetically stable against\ndissociation into As$_4$. We suggest that the Raman spectra might be a means\nfor observing the As$_{20}$ molecule in gas phase.",
