Abstract
THE structure of the resonance lines of silver has been investigated by the method of absorption in an atomic beam, the high resolving power instrument being a Fabry Perot étalon with plate separations between 2 cm. and 10 cm. Each line was found to possess four components ; for the line 5 S½ – 5 2P3/2, 3281 A., the positions were 0.000, 0.013, 0.052 and 0.077 cm.1, and for 5S½ – 5 2P½, 3383 A., they were 0.000, 0.013, 0.058 and 0.084 cm.1. In both lines the two components of shorter wave-length were nearly equal in intensity and very much stronger than the two of longer wave-length, which were also of nearly equal intensity ; photometer curves of the absorption showed that the intensity ratio of the strong lines to the weak lines was approximately 3: 1.
