- Abstract
A delayed ionisation experiment has been carried out on laser excited C70 molecules. Ions and electrons are detected in coincidence to distinguish the ionisation of C70 from that of C68 molecules created by the dominant process, emission of C2. From the time dependence of the C70+ yield and the ratio to the C68+ yield, we can deduce both the dissociation energy, Ed = 9.7 ±0.3 eV, and the pre–exponential factor, Ad = 1.7 ×1020 s-1, in the Arrhenius decay law for C2 emission. The power of photon emission from neutral C70 is also determined.
