| 英文摘要 | We employed a conic-electrode electrostatic ion resonator (ConeTrap) to store the recoil ions (C-60(r+)) resulting from collision between 56 keV Ar-8 divided by ions and C-60 in order to study their stability over a long time range (several milliseconds). The originality of our method, based on the trapping of a single ion to preserve the detection in coincidence of all the products of the collision, is presented in detail. Our results show that C-60 ions produced in such collisions are stable in the considered observation time. By employing the ConeTrap as a secondary mass spectrometer in order to let the ions oscillate only for a single period, we have been able to observe delayed evaporation of cold C-60(3 divided by) ions 20 mu s after the collision. We interpret quantitatively the relative yields of daughter ions with a cascade model in which the transition rates are estimated via the commonly used Arrhenius law, taking into account the contribution of the radiative decay.
