Cross section database for carbon atoms and ions: Electron-impact ionization, excitation, and charge exchange in collisions with hydrogen atoms

Uncertainty estimates for theoretical atomic and molecular data

“…Based on a large set of cross section calculations carried out in the 1980s and 1990s, Suno and Kato constructed recommended data sets that can be fit by simple analytical functions [220]. The recommended data are shown in figure 12 as solid lines.…”

Ionization rate coefficients in warm dense plasmas

“…where B k are constants [16]. The microreversibility relation [19] for the collisional deexcitation and excitation cross sections, respectively, are…”

“…We show that it is necessary to allow for electron degeneracy effects to stop divergent (infinitely large) calculated rates for collisional-radiative processes as electron temperatures drop towards zero. Our work shows how collisional rates (e.g., for carbon [15,16]) can be extended, in principle, to high density, low temperature ionization balance calculations. In particular, we deduce a novel accurate method to allow for three-body effects in degenerate plasmas during collisional ionization and three-body recombination.…”

Modelling of Global Heat Transfer by Local Cooling in Fusion Plasmas

“…where N 1 (t, r) is the total numbers of impurity singly charged species on the magnetic surface per unit length in the direction r, provided by the "shell" model for impurity spreading; L j c and E j ion are the cooling rate and the ionization energy of the species, respectively [31]. Calculations have been performed for the conditions of LIAS in Ohmic TEXTOR discharges, see reference [4] and the radial profiles of the plasma parameters before the LIAS application are presented in figure 11.…”
