Abstract
High-precision measurements of the relative intensities of KX- and γ-rays associated with the decay of the isomer state in 177Lu (T 1/2 = 160.44 days) are performed using a γ spectrometer that incorporates four different types of semiconductor detectors. Detailed analysis of the balance of intensities of the excited levels in 177Lu and 177Hf confirms the consistency of the obtained data. The intensities of the γ- and β—decay branches of the isomer and the internal conversion coefficients of the K-forbidden transitions are determined.
