| 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 C-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 6th ionization stage and energy ranges of about
30-160 eV for neon ions up to the 6th 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. |
