Excitation Curve for Auger Decay of the (1s2s2p2)3D State of C2+ Formed through RTE
The ORNL EN tandem supplied beams of 3.5-9 MeV C3+ ions which were incident on a differentially pumped He target. Auger electrons emitted by fast C2+ ions emerged at 10° (lab) w.r.t. the incident ion beam. They were detected using a two stage spectrometer with kinematic refocusing. An excitation curve was obtained for the (1s2s2p2)3D state Auger decay to the ground state of C3+. The excitation curve peaks at ~ 6 MeV, which strongly supports the notion that the state is formed through resonant transfer and excitation.
