Abstract
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 constantsA andB are determined for eight atomic levels of177,179Hf,181Ta and183W.
