A rate model of inductively coupled argon plasma analyte spectra

Continued Investigations of New Concepts for Improved Spectrochemical Analysis

“…Lovett [61], Boumans and De Boer [62], Blades and Hieftje [63], and many others have proposed models that explain some of the phenomena occurring within the plasma. However, no one theory advanced so far has proven to be completely successful.…”

Rapid evaluation of ion thruster lifetime using optical emission spectroscopy

“…When this system is solved, values for the level populations are generated and in theory, the first major step toward the stated goal of this work is achieved (ref. 15). …”

“…The radiative decay rate is dependent only on the Einstein transition probability, Aji, and the population of the upper state of the atom (ref. 15). …”

“…Each equation balances the rate of population of a level i (rR1jTlj) with the rate of depopulat10n of that level (-RijTlj); the sum of these two terms must, under steady-state conditions, equal zero (ref. 15).…”

“…nT. equation (14) becomes (15 ) s'nce nk = nT = 1, 'f the relat've popu1at'on dens1t1es have been normalized to one.…”
