Abstract

We study the intensity dependence of ionization and fragmentation of buckminsterfullerene (

C_{60}

) in strong laser fields. Our data provide strong evidence that at intensities

≲ 10^{14} W / {cm}^{2}

these processes occur predominantly via multiphoton excitation of the 20 eV plasmon resonance of

C_{60}

. At least two plasmons have to be created to initiate fragmentation or multiple ionization.
