Inter-stage line ratio of He- and Li-like Ti emissions for the electron temperature measurement

Under coronal conditions, the steady state rate-equations are used to calculate the inter-stage line ratios between Li-like ls22p(2p3/2)→ls22s(2S1/2) and He-like ls2p(1P1)→ls2(1So)transitions for Ti in the electronic temperature ranges from 0.1kev to 20 keV. The results show that the temperature sensitivities are higher at the electronic temperature less than 5000 eV and the temperature sensitivities will decrease with the increase of electronic temperature.
