Photoexcitation of Carbon Fullerenes
Abstract
Photoexcitation processes in cold and thermal C60 and C70 molecules in the gas phase were studied. We set up a supersonic beam source of cold fullerenes and use measure the beam energies for helium and krypton as driving gas. We studied thermionic emission from fullerenes following multiphoton pumping using laser pulses of 20 ns, 1 ps, and 150 fs duration. The wavelength dependence for REMPI was investigated from 315 to 335 nm. Multiphoton fragmentation processes and ultrafast dynamics of fullerenes were investigated.. ..
