摘要：

We have been studying the KX and gamma rays spectra in the electron capture decay of Ce-139 -> La-139, which were measured by Ge-spectrometer. The absolute intensity of KX and the 165.8 keV gamma rays has been determined and the known conversion coefficients of the 165.8 keV gamma transition of La-139 were used. The probability P-K was determined as 0.755 +/- 0.054. Our results have good agreement with the results of other works.
