Abstract

<p>Sixty-four lines in the arc spectrum of cesium have been measured interferometrically by utilizing several different light sources, to obtain, in general, wavelengths with an uncertainty of ±0.001 A, and energy levels with an uncertainty of ±0.001 cm<sup>-1</sup>. The energy levels of the individual series have been represented by extended Ritz formulas with a root-mean-square deviation of less than 0.004 cm<sup>-1</sup>. The value of the series limit derived from these formulas is (31 406.450±0.030) cm<sup>-1</sup>. Eight terms of the <sup>2</sup>F series have been represented by a two-parameter polarization formula with a rms deviation of 0.04 cm<sup>-1</sup>.</p><p>The hyperfine components of the 6<sup>2</sup><i>S</i><sub>½</sub>, 8<sup>2</sup><i>S</i><sub>½</sub>, and 6<sup>2</sup><i>P</i><sub>½</sub> levels have been resolved. By making use of the theoretically predicted dipole intensity relations, rough values of the splitting factors in the unresolved <sup>2</sup><i>S</i> and <sup>2</sup><i>D</i> states have been obtained which agree with the values predicted on the basis of the Fermi-Segrè-Goudsmit formula. In the forbidden transitions <i>n</i><sup>2</sup><i>D</i><sub>3/2,5/2</sub>-6<sup>2</sup><i>S</i><sub>½</sub>, the theoretical quadrupole intensity relations were used to obtain the splitting factors of the <i>n</i><sup>2</sup><i>D</i><sub>3/2,5/2</sub> states. These splitting factors differed markedly from those predicted by the Fermi-Segrè-Goudsmit formula.</p>
