With the conic electrode trap, the lifetime of Cr+60 was measured in 56 keV Ar8+ - 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. While for the recoil ions The outgoing projectiles Ar (8-s) +, on which s captured electrons are stabilized, are selected by an electrostatic analyzer.
