Hyperfine Constants

Recent molecular-beam, laser-rf, double-resonance measurements of the hfs intervals in the X2Σ ground state of CaBr have been supplemented with laser scans of the hfs of sub-Doppler B ↔ X optical lines in a molecular beam to provide greatly improved values for the hfs constants of the excited B2Σ state. The values b = 11.8 ± 0.4 MHz and eqQ = 30.4 ± 1.0 MHz are reported for the hyperfine constants of Ca79Br in its B2Σ2, ν′ = 0 state; c is found to have a magnitude not more than about 10 MHz, and may be negative.

Level 2

The hyperfine structure of the level 2 2P1/2 of both 6Li and 7Li has been investigated by means of the optical–radio–frequency double-resonance method. The following values were obtained for the magnetic interaction constants of the two isotopes:[Formula: see text]The gJ value for the 2P1/2 level was found to be −0.6668 ± 0.0020.
