Summary:
Ten radionuclides, including isomers, from ¹⁷²Ta to ¹⁸°Ta and {sup 180m}Hf were produced by photon interactions with a sample of elemental tantalum and measured by counting photons using a high-resolution detection system. Relative yields of these radionuclides were obtained. In addition, precision half lives were obtained for {sup 175,176,180}Ta and {sup 180m}Hf. Those obtained for the three Ta isotopes agree with previously reported values. For {sup 180m}Hf, the present measurements resulted in a half life determination of 6.05{plus minus}0.06 hr, or about 10% longer than the currently adopted value for this half life.
