Phys. Rev. Lett. 98, 193401 (2007) [4 pages]Direct Measurement of Internal Energy of Fragmented C60Received 17 November 2006; published 10 May 2007 A new experimental approach has been investigated to measure directly the internal energy of fragmented C60. Doubly charged C602+* prepared in collisions H++C60→H-+C602+* decay by evaporation of C2 units. We have measured the internal energy distribution of the transient C602+* for each decay channel by analyzing the kinetic energy loss of the scattered anion H-. This method offers an experimental opportunity for studying the fragmentation dynamics of more complex systems such as larger clusters and biomolecules under internal energy controlled conditions. © 2007 The American Physical Society URL:
