Deviation of the level populations of iron atoms and ions from the boltzmann distribution in an inductively coupled plasma. Part 1. Spatial and power dependences
Abstract
The deviation from the Boltzmann distribution was studied for the excitation of iron atoms and ions in an inductively coupled plasma supported by a Meddings–Anderson–Kaiser torch. Its spatial and power dependences are discussed in conjunction with such properties as curvature of the Boltzmann plot, tangential temperature and relative number densities of the iron atoms and ions.
