Abstract
We investigate the time dependence of carbon cluster ions, formed via thermionic emission from photoexcited fullerenes (C60 and C70). By pul sing the extraction field, we are able to observe delayed ions formed as late as 100 mus after excitation at 532 nm, 355 nm, or 266 nm. All even-sized clusters in the range 36 less-than-or-equal-to n less-than- or-equal-to 70 undergo thermionic emission.
