Abstract In order to search for traces of the181Ta(α, π −)185Os reaction a foil stack of very pure tantalum was bombarded with anα-beam of 173 MeV. A radiochemical separation method was applied to four parts of the stack. So two sources corresponding to energies above and below the (α, π −) threshold were obtained and searched for contents of185Os. Using a well shielded Ge(Li) detector weak 646 keV transitions belonging to185Os were observed for all samples. Since the origin of this activity is uncertain for the samples below threshold only an upper limit of 100 nb can be set for the (α, π −) reaction on181Ta above threshold.
