Radiative lifetimes of nine of the levels np 'P:/,, np 'D:,,. s,z andnp 'D:/, in the homologous ions Ar I1 (n = 4), Kr I1 (n = 5 ) and Xe I1 (n = 6) have been measured with the beam-laser method. The measured lifetimes are compared with lifetime values from other experimental and theoretical works and a thorough discussion of the discrepancies between the results obtained with different techniques is made. Older measurements of transition probabilities are put on an accurate scale using the new lifetime values. The f-values of some strong transitions from levels in the np configuration in Ar 11, Kr I1 and Xe I1 are compared and are found to be approximately equal.

“…Consequently, electron temperature increases via the three-body recombination reaction. Figure 10(a) shows the relationship between the electron temperature (kinetic electron temperature T e ) measured by LTS and electron excitation temperature (T exc ) that was also called configuration temperature [30] measured by OES with the discharge current at the different background pressures. It is clearly seen that both T e and T exc increase with the increase of discharge current, but T exc is always higher than T e .…”

As advanced linear plasma sources, cascaded arc plasma devices have been used to generate steady plasma with high electron density, high particle flux and low electron temperature. To measure electron density and electron temperature of the plasma device accurately, a laser Thomson scattering (LTS) system, which is generally recognized as the most precise plasma diagnostic method, has been established in our lab in Dalian University of Technology. The electron density has been measured successfully in the region of 4.5×10 19 m −3 to 7.1×10 20 m −3 and electron temperature in the region of 0.18 eV to 0.58 eV. For comparison, an optical emission spectroscopy (OES) system was established as well. The results showed that the electron excitation temperature (configuration temperature) measured by OES is significantly higher than the electron temperature (kinetic electron temperature) measured by LTS by up to 40% in the given discharge conditions. The results indicate that the cascaded arc plasma is recombining plasma and it is not in local thermodynamic equilibrium (LTE). This leads to significant error using OES when characterizing the electron temperature in a non-LTE plasma.
