Rate coefficients for ionization balance at coronal equilibrium

FLYCHK rate coefficients [cm3/s] of direct collisional ionization(ci), excitation autoionization(ea), radiative recombination(rr) and dielectronic recombination rates(dr) of each ion are calculated as a function of temperature[eV] for plasma modeling applications. The radiative cooling coefficients per charge state per electron density [eV-cm3/s] for each ion are also listed for line radiation (bb) and recombination radiation (bf). For a radiative cooling rate, one should multiply by electron density[cm-3] and the density of the charge state[cm-3]. Read the Rate Coefficients Table. Note that all caclulations are done at Ne=1cm-3. For more information, please check the section on "About FLYCHK rate coefficients".
