Measurement of Transition Probabilities in the Cl I, II and C I Spectra

Abstract

Using a vortex-stabilized arc in chloroform, transition probabilities have been obtained for all classified Cl I lines from 3900-5200 Å and for the strongest Cl II lines in this region. New C I measurements are reported in satisfactory agreement with means from previous works. A strong continuum associated with the chloroform plasma is attributed mainly to the Cl I recombination spectrum in the 3900-5200 Å region. Transition probabilities for Cl lines average 23% above those of Hey.
