Outline of Final Research Achievements

When one applies ultrafast photoelectron imaging (UPI) to photoisomerization reaction, one needs to unambiguously assign photoionization signals from a molecule in an electronic excited state. In this study, we have found that "hidden" cationic states, which have not been taken into account in UPI, are clearly observed in a photoelectron spectrum of an excited-state molecule when using vacuum ultraviolet probe pulses. We presented their general importance in UPI for the first time.
