Dielectronic recombination of Be-like argon at the CSRm

Dielectronic recombination of Be-like argon at the CSRm

Electron-ion recombination of Be-like 40Ar14+ has been measured for the first time at the main Cooler Storage Ring (CSRm) at Heavy Ion Research Facility in Lanzhou (HIRFL), China. The absolute rate coefficients over 0-60 eV electron-ion energy were obtained and all the resonances associated with the...

Zusammenfassung:Electron-ion recombination of Be-like 40Ar14+ has been measured for the first time at the main Cooler Storage Ring (CSRm) at Heavy Ion Research Facility in Lanzhou (HIRFL), China. The absolute rate coefficients over 0-60 eV electron-ion energy were obtained and all the resonances associated with the Δn=0 dielectronic recombination channel (2s2→2s2p) were studied. In addition to radiative and dielectronic recombination, the recombination spectrum also shows strong contributions from trielectronic recombination channel (2s2→2p2). The experimental method and preliminary results are presented.
