|Title:||New intensity formula for ionic spectra|
Spectral Tables UV-IR
Optical Emission Spectrometry
|Abstract:||The new intensity formula in optical emission spectroscopy for the use of ions has been developed. The formula is built up on four different parts: The <i>C</i>-factor, wavelength dependence term, ionization energy term and the Planck factor. The method used in this very paper is the absolute intensity method which is described in many papers in the past. The experimental data are coming from NBS-tables of spectral intensity data from arc measurements of different elements. Nice linear relationships are obtained for oxygen ions in energy ranges of about 25-200 eV up to the 6<sup>th</sup> ionization stage and energy ranges of about 30-160 eV for neon ions up to the 6<sup>th</sup> ionization stages. A general formula for ions is presented including a sum of ionization energies from different ionization stages in the ionization energy term. The electron temperature has also been determined for atoms and ions of many elements. These electron temperatures are found to be in agreement with the energy distribution of secondary electrons from many experimental results from the literature.|
