Description

To experimentally obtain the transition probabilities of Ar atom, spectroscopic measurements were carried out on Ar arc plasma for melting metal by using highly sensitive multichannel detector. Then the Boltzmann plot method was newly adopted for determination of transition probabilities, using the values recommended by Wiese et al as starting values. The Boltzmann plot obtained by using present transition probabilities was linear at high correlation coefficient over 0.9 in spite of the variations of plasma temperature, working gas pressure and metallic vapor. Therefore, it was concluded that new transition probabilities can be used in temperature measurement of Ar arc plasma.
