摘要：

Double ionization of CO and N2 induced by photons from a synchrotron radiation source has been studied in an electron-electron coincidence experiment. A new technique for this type of study has been developed wherein only electrons with near-zero energy are detected by the use of the penetrating field method. In this way high sensitivity and energy resolution have been attained and this has allowed vibrational structure to be observed for the doubly-charged ions of both these molecules and accurate energies for the states to be obtained.
