  1. The Smallest Stable Fullerene, M@C28 (M = Ti, Zr, U)Gregory S. Boebinger, Florida State University, DMR 0654118Ion Cyclotron Resonance Facility Broader Impact: The experimental detection of new fullerene species immediately opens the door to spectroscopic studies. The nontoxic nature of Ti allows safe experimental attempts for its macroscopic synthesis. Titanium encapsulation offers an attractive route toward synthesis of the smallest fullerenes that are not available as empty cages. Fullerenes have been identified in outer space, and the atom(s) trapped inside them can be markers for determining the age of stars and galaxies. We thank John P. Quinn for instrument maintenance and experimental assistance, Michael A. Duncan for cluster source design, and Patrick W. Fowler for discussions. This work was funded by NSF DMR-0654118, NSF CHE-1019193, Florida State University Research Foundation, Spanish Ministry of Science and Innovation (Project No. CTQ2011-29054-C02-01) and the Generalitat de Catalunya (2009SGR462 and XRQTC). Facilities: NHMFL cluster ion source 9.4 tesla FT-ICR mass spectrometer. Citation: Dunk, P. W.; Kaiser, N. K.; Mulet-Gas, M.; Rodrigues-Fortea, A.; Poblet, J. M.; Shinohara, H.; Hendrickson, C.
