Yp. Gangrskii et al., PRECISION-MEASUREMENTS OF HYPERFINE SPLITTING OF OPTICAL-LINES BY RESONANCE LASER SPECTROSCOPY, Measurement techniques, 40(6), 1997, pp. 577-582
Precision measurement of hyperfine splitting of optical lines in atom
or ion spectra is discussed. An experimental measurement technique bas
ed on laser resonance excitation of the investigated lines is describe
