Abstract
Gas phase C-60 is resonantly excited using picosecond infrared (IR) pulses from a free electron laser. The excitation can be very high, reaching level s where the thermal emission of electrons from C-60 is observed. The excita tion is much more efficient when the IR radiation is chirped to lower frequ encies during the excitation process. The excitation process is modeled and the results are compared to the experiment. (C) 1998 Optical Society of Am erica.
