Abstract

A statistical (maximum entropy) computation can reproduce the observed energy dependence of the C₄H₄⁺/C₆H₅⁺ and C₃H₃⁺/C₆H₅⁺ branching ratios for monoenergetic C₆H₆⁺ ions with 4.7-5.5 eV of excess energy. Corresponding results for the perdeuterated parent ions are presented. Agreement with experiment is poor for the C₆H₄⁺/C₆H⁵⁺ branching ratio and possible reasons are discussed. At a sharp value of the excess energy the computed mass spectrum is quite sparse showing clearly the superiority of energy-resolved experiments as probes of the dynamics.
