[en] The hyperfine structure of the ³D₁ and ¹D₂ states of the 4d⁹ 5s configuration of ¹⁰⁵Pd have been determined by use of intermodulated fluorescence spectroscopy in an atomic beam which has been produced by a hollow cathode effusive beam source. Together with previous results by other workers a consistent description of the hyperfine structure in the 4d⁹ 5s configuration has been given. From the isotope shift data of some transitions to the 4d⁹ 5p configuration relative values for the nuclear field shift parameter λ^AA' could be obtained. (orig.)
