Up: Temperature dependence of Stark


6 Conclusion

Within the experimental accuracy and reliability of the theoretical approximation, agreement between measured and calculated Stark FWHM values for the 463.054 nm NII spectral line was found over a wide range of electron temperatures. The only exception is at 6500 K electron temperature where the modified semiempirical formula predicts 1.5 times higher value in comparison to existing experimental result (Perez et al. 1997). Therefore, the isolated 463.054 nm NII spectral line can be recommended as convenient spectral line in a plasma diagnostics.
