Abstract. Energies and intensities of Kx(Ho),Kx(Dy) and γ-quanta with energies 59.98 and 86.79 keV from the decay 160Er → 160m,gHo → 160Dy are measured with a high accuracy. The branching factor for the isomeric state 160mHo(2-) is found from the results of the measurements. The value 0.733(30) is obtained for the E3 transition to the ground state.
