Abstrakt

Positive and negative fullerene ions have been stored in a heavy-ion storage ring. The authors found confinement times (storage lifetimes) of the order of 2 to 10 s, the limit being set by collisional destruction in the background gas. The data also show a short decay time of the order of some milliseconds. This component was considerably longer for the negative C60 and C70 ions than the neighboring negative C58 and C68 ions. The authors discuss the possible processes that may account for the observation of the ms-decay times. The present technique may provide an excellent way to produce and study cold clusters
