Optogalvanic detection of complex Zeeman patterns in a hollow-cathode lamp is investigated. Uranium lines with J/sub 1/ = 6 and J/sub 2/ = 7 are resolved, with our best results obtained using intermodulate optogalvanic spectroscopy (but this scheme is applicable only to lines giving strong signals). This detection method has a 40-MHz resolution, so a magnetic field of 0.1 T is sufficient to resolve most patterns. Weak lines can be studied with modulated optogalvanic spectroscopy. However, the stronger field required in this case perturbs the discharge. Although they are impractical for the measurement of component relative intensities, these detection methods may find applications in the determination of Lande g factors.
