The intensity changes of all the important spontaneous emissions of Kr I and Kr II in visible region are examined, when the 5682Å laser transition (5p 4 D 5/2 →5s 2 P 3/2 ) in Kr II is interrupted by a rotating chopper. The strong positive cross-modulations are observed in the lines which start from 5p 4 D 5/2 state of Kr II. The cross-modulations of the lines which end on 5 s 2 P 3/2 state of Kr II are not so strong. But certain degree of cross-modulations are observed in some of the lines of Kr II which have no direct connection to the laser states. No cross-modulation is observed in the Kr I lines.

The first reported study of a fluorescence spectrum of a metal vapor resonantly excited by vacuum-ultraviolet radiation has been made in Ba ii. Seven Ba ii fluorescent transitions have been identified for Ba vapor excited by 584-Å radiation. The intensities of these transitions are consistent with the population distribution of excited Ba ii observed by using photoelectron spectroscopy. No detectable Ba ii fluorescence was observed when 736–742-Å excitation was used.
