摘要
The branching ratios for the dissociative recombination of hydrocarbon ions with general formula C4Hm+ have been measured using the storage ring technique. It is found that the isomeric state can in some cases give an indication of the preferred dissociation pathways but there are exceptions to this, namely C4H+ and C4H5+. (C) 2004 Elsevier B.V.
