Chemical effects on the K-i/K-j (i = alpha(2), beta, beta(1), beta(2); j = alpha, alpha(1), beta(1)), L-i/L-alpha (i = l, beta, gamma) and L-i/K-j (i = l, alpha, beta, gamma; j = alpha(1), alpha(2)) x-ray intensity ratios for (Hf) compounds were investigated. The samples were excited by 123.6 keV gamma-rays from a Co-57 annular radioactive source. K and L x-rays emitted by samples were counted by an Ultra-LEGe detector with a resolution of 150 eV at 5.9 keV. We observed a chemical effect on the L-i/L-a and L-i/K-j x-ray intensity ratios for Hf compounds. However, for the K-i/K-j intensity ratios, dependence on the chemical state of Hf compounds is almost negligible. The experimental values have been compared with the theoretically calculated values of pure Hf.
