Time-Resolved Dynamics on the Giant Plasmon Resonance of C<sub>60</sub>

ORAL

Abstract

We have investigated the time-resolved ionization and fragmentation dynamics of C60 using intense, ultrashort radiation from the FLASH free-electron laser tuned to the giant plasmon resonance near 20 eV. The dynamics were probed using a one-color pump-probe technique in combination with a reaction microscope. We will present a systematic study of the time-dependent kinetic energies of the atomic and molecular ionic fragments in addition to ion-ion coincidence channels as a function of photon energy, pulse intensity, and pulse length. Our results indicate a strong pulse intensity dependence of the kinetic energies and yields of the carbon monomer and dimer ions, along with a photon energy dependence in the yield of the carbon dications. We will discuss the possible mechanisms for the observed dynamics.
