Abstract:
We have calculated Xray and UV spectra of the Belike Fe (FeXXIII) ion using collisionalradiative model including all finestructure transitions among the 2s^2, 2s2p, 2p^2, 2snl, and 2pnl levels where n=3 and 4, adopting data for the collision strengths by Zhang & Sampson (1992) and by Sampson, Goett, & Clark (1984). Some line intensity ratios can be used for the temperature diagnostic. We show 5 ratios in UV region and 9 ratios in Xray region as functions of electron temperature and density at 0.3 keV leq T_e leq 10 keV and n_e =1 10^{25} cm^{3}. The effect of cascade in these line ratios is discussed.
