Dielectronic recombination in highly charged He-like ions

Angular correlations in radiative cascades following resonant electron capture by highly charged ions

“…Moreover, DR studies play an important role in understanding the quantum electrodynamic (QED), many-electron, or even hyperfineinteraction effects in heavy atomic systems [8][9][10][11]. In order to probe these effects, a large number of DR experiments have been performed at storage ring and electron-beam ion-trap (EBIT) facilities for various charge states of ions and collision energies [12][13][14][15].…”

Experimental study of the deep-lying dielectronic recombination resonances of He-like germanium ions

“…The electron beam ion trap (EBIT) is an ideal environment in which to study this process [4]. Since the introduction of the first EBIT in 1986, experiments with He-like ions such as Ni 26+ , Mo 40+ and Ba 54+ [4], Ar 16+ [5,6], Fe 24+ [7,8], Ti 20+ [9], Kr 34+ [10], among others, have been reported using this method. The state-resolved DR process of Ar 16+ has been investigated and DR through two-electron-one-photon (TEOP) correlative stabilization observed [6] using the Freiburg EBIT [11].…”

The effects of quantum interference between direct and resonant photorecombination of H-like Ar17+ions

“…The study of RR is important for understanding fundamental atomic processes in astrophysics and experimental plasmas, and in applications of inertial confinement fusion [1]. The strengths of different radiative processes in an electron beam ion trap (EBIT) are determined by normalizing those x-ray intensities to the RR x-ray intensity using a theoretical RR cross section [2,3]. The other process is the well-known resonant photorecombination, i.e.…”
