Abstract

Delayed ionization of fullerenes C60 was discussed. A competition between delayed ionization and neutral fragmentation on the microsecond time scale was studied using ultraviolet (UV) laser excitation experiments. The ionization rates were calculated for three competitive decay channels that included therionic emission, neutral fragmentation, and radiative cooling. Unreasonably high values of 10 μs obtained in combination with strong deviation from power law behavior for delay times were attributed to the electronically excited fullrenes in the lowest triplet state.
