Abstract
The radiant flux in the Hg resonance lines just inside the wall of a lamp with an inside diameter of 35–36 mm is given for currents 0.4−2.0 amp and various bulb temperatures and rare gas fillings. The intensity of the 1850 line ranges from 12 to 34% of that of the 2537 one, with the highest ratios occurring when both arc current and bulb temperature are at the upper end of the ranges used. Since this result is contrary to what one would expect with single‐stage excitation of the 1850 line, one must assume that this line is excited mainly by 63P–61P1 transitions when arc current and mercury vapor pressure are both relatively high. A rough estimate of the frequency of 63P2–61P1 transitions, compared to those from the ground level to 61P1 confirms this conclusion.This publication has 1 reference indexed in Scilit:
