Structure and QED effects for and
levels
are calculated for lithiumlike U89+ trough neonlike U82+,
lithiumlike Th87+ trough neonlike Th80+ and lithiumlike
Bi80+ trough neonlike Bi73+. The results of the first two
sets are compared with recent measurements of the
transition energy in 3 to 10-electron ions. Good agreement with
experiment is found for most of the observed lines. Forty-one
possible transitions are calculated for each ion in the eight
ionization states, in the experimental energy range. Twenty-eight of
these transitions have not been observed, nor calculated
previously. We also calculate transition rates, branching ratios,
excitation and ionization cross sections and confirm that the
thirteen experimental observed transitions correspond to the ones
with highest relative intensities. However, we find nineteen more
transitions that could be measured in a more sensitive experiment.
