Özet

In this study, the L-1 -> L-2, L-1 -> L-3, and L-2 -> L-3 Coster-Kronig (CK) transition probabilities (f(12),f(13), and f(23)) for Hf compounds were investigated. The samples were excited by 59.5 keV gamma-rays from a Am-241 annular radiative source. L X-rays emitted by samples were counted by an Ultra-LEGe detector with a resolution of 150 eV at 5.9 keV. In addition, it was observed a chemical effect on the CK transition probabilities for Hf compounds. The semi-empirical values of f(12), f(13), and f(23) CK transition probabilities have been compared with the semi-empirical, theoretical and experimental data for pure Hf, respectively.
