Abstract

The optical spectra of

U^{4 +}

and

U^{5 +}

doped into hafnon (HfSi

O_{4}

) and thorite (ThSi

O_{4}

) are reported. However, no significant information was obtained on the validity of a previous crystal-field fit of the absorption spectrum of

U^{4 +}

doped into zircon (ZrSi

O_{4}

). New experiments confirm the interpretation of Judd and Runciman of the Zeeman behavior of zircon:

U^{5 +}

.
