Abstract:
We have calculated the dielectronic recombination rate coefficients from Li-like Ne (Ne^{7+}) ions to Be-like Ne (Ne^{6+}) ions for selected excited states of Ne^{6+} ions. A collisional-radiative model (CRM) for Ne^{6+} ions is constructed to calculate the population density of each excited state in non-equilibrium ionization plasmas, including recombining processes. NeVII spectral line intensities and the radiative power loss are calculated with the CRM. A density effect caused by collisional excitation from the metastable state 2s2p ^3P is found at an electron density of 10^5 - 10^{17} cm^{-3}. The collisional excitations between excited states become important at high electron temperature T_e >~ 100eV.
