摘要
Fragmentation of (OCS)(3+) and (OCS)(4+) produced by 120 keV Ar8+ collision was studied by using a position-sensitive time-of-flight (PS-TOF) method. We identified stepwise processes involving CO2+ and CS2+ metastable species as well as the concerted process (simultaneous breakup of the two bonds). For the (OCS)(4+) events, the stepwise processes were found for fragmentation channels containing a doubly-charged terminal atom.
