The Tm/sup 173/ nuclide was produced by the ( gamma ,p) reaction by using an intense bremsstrahlung from a linear electron accelerator. A Yb/sup 174/ target enriched to 99% was used. The radiations from Tm/sup 173/ were measured by means of a betaand gamma-scintillation spectrometer. Two beta-ray groups with end-point energies of 1.26 and 0.86 Mev were found, and K x-ray, 395 and 460 kev gamma rays were observed. The excited states at 395 and 460 kev in Yb/sup 173/ were identified as 1/2/sup +/STA651! and 1/2/sup -/STA521! intrinsic states, respectively. It was found that the 395-kev state is an isomeric level with a half life of 2.9 mu sec. The assignments were made with the aid of electron--K x-ray and electron-beta coincidence methods. (auth)
