Abstract: | Two-photon transitions have been observed from the 62S ground state of atomic cesium to selected higher lying n2D levels up to n = 19. The transitions were excited by a narrowband dye laser pumped by a nitrogen laser and detected by a space charge limited cesium vapor photodiode. The fine structure intervals of the n2D levels for n = 15, 17 and 19 were measured by direct comparison with the ground-state hyperfine interval, and the line strength ratios of the fine-structure components were measured and compared with the predictions of a simple theoretical model. |
