Original scientific paper
We present the results of spectroscopic studies of the high pressure K-Na-Cd-Ar
discharge lamp. They were compared with the results of K-Hg-Ar discharge lamp. The
interesting part of the spectrum was the region around the second resonance potassium line
(5p-4s transition) at 404.4 nm and 404.7 nm. There we observed a group of satellite bands
which we attribute to the KCd excimer transitions. In the red part of the spectrum a broad
KCd diffuse band was observed with peaks at 630 nm and 640 nm. From the comparison with
the KHg system, we ascribe these bands to the 22P-X2
S+ electronic transitions.
