Bombardment of Ho/sub 2/O/sub 3/ with N/sup 14/ ions in the Berkeley heavy-ion linear accelerator resulted in the discovery of new isotopes of tantalum which have been assigned as Ta/sup 173/ and Ta/sup 174/. They have half- lives of 3.7 hr and 1.3 hr, respectively. Tantalum-172 was not observed and is believed to have a half-life shorter than 30 minutes. Gamma-ray spectra were obtained for these two isotopes and for Ta/sup 175/ Tantulum-175, with an 11-hr half-life, was also produced by 48-Mev alpha-particle bombardment of Lu/sub 2/O/ sub 3/, and its conversion-electron spectrum was studied. From these data a decay scheme is proposed using nine of the observed transitions and assigning spins to three members of the ground-state rotational band. (auth)
