Ar-ion sputtering is successfully used to produce intense atomic beams of refractory elements. The population in the ground and low metastable states of Ta 1 is investigated for the sputtered atoms. Isotope shifts and hyperfine structures of seven transitions have been measured for the stable isotopes of Hf, Ta and W. The hyperfine coupling constants A and B are determined for eight atomic levels of177,179Hf,181Ta and183W.
