Abstract :
Linewidth broadening and saturation intensity measurements of the Kr 84 1s/sup 2/-2p/sup 8/ transition have been carried out with opto-galvanic spectroscopy. The Doppler-free natural linewidth of Kr 84 and Kr 83 has been determined to be 56 MHz. Transitions were observed in many other isotopes of Kr, with shifts of several GHz from the line of Kr 84.<>
