Observation of strong two-electron-one-photon transitions in few-electron ionsAtomic and Molecular Physics, and OpticsNo. 05K13SJ2 Project No. 266229290 UID/FIS/04559/2020 NRF-2016R1A5A1013277 DE-AC52-07NA27344We resonantly excite the K series of O5+ and O6+ up to principal quantum number n=11 with monochromatic x rays, producing K-shell holes, and observe their relaxation by soft-x-ray emission. Some photoabsorption resonances of O5+ reveal strong two-electron-one-photon (TEOP) transitions. We find that for the [(1s2s)15p3/2]3/2;1/2 states, TEOP relaxation is by far stronger than the radiative decay and competes with the usually much faster Auger decay path. This enhanced TEOP decay arises from a strong correlation with the near-degenerate upper states [(1s2p3/2)14s]3/2;1/2 of a Li-like satellite blend of the He-like Kα transition. Even in three-electron systems, TEOP transitions can play a dominant role, and the present results should guide further research on the ubiquitous and abundant many-electron ions where electronic energy degeneracies are far more common and configuration mixing is stronger.DF – Departamento de FísicaLIBPhys-UNLRUNTogawa, M.Kühn, S.Shah, ChintanAmaro, PedroSteinbrügge, RenéStierhof, J.Hell, N.Rosner, MariekeFujii, K.Bissinger, M.Ballhausen, R.Hoesch, M.Seltmann, J.Park, SungnamGrilo, FilipePorter, F.
