Özet

K shell X-ray production cross-sections (sigma(K alpha) and sigma(K beta)) have been measured for some elements in the atomic number range 28 <= Z <= 40. Measurements have been carried out at 16.896 keV excitation energy using secondary source. K X-rays emitted by samples have been counted by a Si(Li) detector with 160 eV resolution at 5.9 keV. The values of K-shell fluorescence yields (omega(K)) have been evaluated for the same elements. The results obtained for K X-ray production cross-sections and fluorescence yields have been compared with the theoretically calculated values and other available semiempirical values.
