STARK BROADENING OF THE SPECTRUM LINE 4603 A. OF LITHIUM
The lithium line at 4603 A arises from a 2p-4d transition. Under the action of a uniform electric field this line is displaced to longer wave-lengths and two other lines appear, one due to a 2p-4p transition and the other to a 2p- 4f transition. The 2p-4p transition gives a weak line at 4636 A for vanishingly weak electric fields, shifting to longer wave-lengths at increasing field strengths. The 2p-4f transition gives a line at 4602 A for vanishingly weak fields, shifting to shorter wave-lengths at increasing field strengths. In the actual experiment the shock wave Mach number was 9.2, and the initial pressure of the argon 5 mm mercury. This gives a temperature of 11500 deg k and ion density of 1.6 x 10/sup 17/ per cc behind the shock wave reflected from the end of the tube. (P.C.H.)
