Transition probabilities using branching ratios determined with the Kitt Peak FTS lifetimes obtained by laser and other techniques - lanthanides and U II.*

Our studies at Lawrence Livermore National Laboratory (LLNL) of lanthanide and actinide spectra with the Kitt Peak National Solar Observatory (KPNO) 1 m Fourier transform spectrometer (FTS) have included both intensity for branching ratio (BR) determination (transition probability) and frequency observations using hollow cathodes (HC) and/or electrodeless discharge lamps (EDLs) as sources. The elements we have observed, the purpose of the study and the sources used are given in Table 1.
