Abstract: The precise γ-ray intensities of the transitions following the decay of 160-day isomeric state in ¹⁷⁷Lu have been measured by using two different types of HPGe-detectors. The values of the internal conversion coefficient and penetration parameter λ for E1-transition with the energy of 55 keV were determined from intensity balance of 21/2^- 1260 keV level in ¹⁷⁷Hf.

Keywords: radioactivity, ^177mLu, γ-spectra, HPGe-detectors, measurements I(γ), internal conversion, penetration parameter.
