Abstract:

Np-doped Na-charge compensated crystals of PbMoO4 were grown by the Czochralski method. The absorption spectrum between 5000 and 25,000cm and the fluorescent spectrum between 4000 and 7000cm were obtained. The free-ion parameters obtained from a least squares fit to the five lowest free ion levels neglecting configuration mixing are E1 2970cm E2 14.01cm E3 312.1cm and xi5f 2089.2cm. The r.m.s. deviation for this fit was 22cm. A first order field perturbation calculation was also carried out.
