Storage Ring Measurement of the C IV Recombination Rate Coefficient

摘要: The low-energy C IV dielectronic recombination (DR) rate coefficient associated with 2s → 2p Δn = 0 excitations of this lithium-like ion has been measured high-energy resolution at the heavy-ion storage ring TSR Max-Planck-Institut fur Kernphysik in Heidelberg, Germany. experimental procedure and especially detection probabilities for high Rydberg states produced by are discussed detail. From data a Maxwellian plasma is derived ±15% systematic uncertainty parameterized ready use plasma-modeling codes. Our result benchmarks below 104 K where DR occurs predominantly via III (1s22p4l) intermediate existing theories differ orders magnitude. Furthermore, we find that, to within our 15%, total radiative can be represented incoherent sum Pequignot coworkers.
