Precision electron-gamma spectroscopic measurements in the decay of 177Lu

Appl Radiat Isot. 2011 Jun;69(6):869-74. doi: 10.1016/j.apradiso.2011.02.012. Epub 2011 Feb 26.


Complete precision electron and gamma spectroscopy measurements were undertaken for the 6.647 day decay of (177)Lu. Precision measurements of the K, L, and M internal conversion coefficients (ICCs) were made using a high transmission Mini Orange Electron Spectrometer coupled to a Si(Li) detector. We also report energies and intensities of the 6 gamma rays measured with a large volume 60 cc HPGe detector and 9 X-rays with better precision. The energies and intensities of the beta transitions from (177)Lu leading to the levels in the daughter (177)Hf were calculated by transition intensity balance at the levels.
