Tantalum, bombarded by 660-Mev protoris, was chemically separated from reaction products (mostly rare earths and hafnium) and investigated with an automatic scintillation spectrometer. The intensities of the strongest gamma lives of the tantalum fraction decreased with an 8 to 11 hr period. Energies and relative intensities of gamma lives are tabulated and gamma spectra up to 400 kev and 3.1 Mev are plotted. Two isotopes of tantalum were found: Ta/sup 176/(T = 8 hr) and Ta/sup 175/ (T = 11 hr). The intensities of various lives at 1.5 Mev and above diminished with the identical time period of 8 plus or minus 1 hr. The mass difference of Ta/sup 176/ and Hf/sup 176/ which is over 3 Mev, was evaluated using the data obtained for the Ta/sup 176/ spectrum. (R.V.J.)
