Fine- and hyperfine-structure constants of thenpP3(n=2−5)terms ofLi6,7II

Using a velocity-independent analysis of zero-field quantum beats in time-resolved decays of the $\mathrm{np}{}_{}{}^3{}_{}{}^{}P\mathrm{}(n=2-5\mathrm{})\mathrm{}$ terms of ${}_{}{}^{6,7}{}_{}{}^{}\mathrm{Li}$ II, we have obtained measurements of (a) the fine-structure separations $J=0\mathrm{}$ to $J=1\mathrm{}$ and $J=0\mathrm{}$ to $J=2\mathrm{}$, (b) the hyperfine contact terms, and (c) the dipole terms of the hyperfine interaction. Our accuracy is a few parts in ${10}^3$ for some of the constants. In some cases, the fine-structure constants are in significant disagreement with the calculations of Accad, Pekeris, and Schiff. The hyperfine constants for the $n=2\mathrm{}$ term are close to recent many-body calculations.
