Optogalvanic spectroscopy of the hyperfine structure of the $5p^{6}5d$ ${}^2{D}_{3/2,5/2}$ and $5p^{6}4f$ ${}^2{F}_{5/2,7/2}^o$ levels of La III

We measure the hyperfine structure of the $5p^{6}5d$ ${}^2{D}_{3/2}$, $5p^{6}5d$ ${}^2{D}_{5/2}$, $5p^{6}4f$ ${}^2{F}_{5/2}^o$, and $5p^{6}4f$ ${}^2{F}_{7/2}^o$ levels in doubly-ionized lanthanum…
