Popis: The decay of Tm 167 was investigated by means of coincidence measurements. We found new gamma transitions with energies of 270 keV and 325 keV and intensities compared with the intensity of the 532 keV transition of 1.3 · 10 −2 and 2.5 · 10 −2 , respectively. Estimating the K conversion coefficients the character of both transitions was determined to be E1. The hindrance factors for E1 transitions of the ( K 0 −2) vibrational states in Ho 165 , Er 167 and Re 187 were calculated, the order of magnitude being 10 3 to 10 6 .
