Fine-structure splittings in high-lying ~2F states of rubidium via three-step laser spectroscopy

摘要

Three-step laser spectroscopy has been used to measure six additional fine-structure splittings in the n~2F states of~(87)Rb for 11≤ n 16. When combined with our previous measurements for 4≤n10, they constitute a continuous sequence of 13 measurements suitable for comparison to fine-structure calculations in heavy alkali-metal atoms where relativistic effects, core polarization, configuration mixing, and electron correlation are important.
