摘要
With the conic electrode trap,the lifetime of C^(r+)_(60)was measured in 56 keV Ar^(8+)-C60 collisions.The outgoing projectiles Ar^((8-s)+),on which s captured electrons are stabilized,are selected by an electrostatic analyzer.The ejected electrons and the recoil ions were extracted from the interaction region by a high transverse electric field E=1 kV/cm.After extraction the electrons were accelerated towards a semiconductor detector(PIPS)biased at 20 kV,which gives the information on the number of emitted electrons in the react.
