Measurements of K-shell X-ray production cross-sections and fluorescence yields for some elements in the atomic number range 28≤Z≤40

• KαKα and KβKβ X-ray production cross-sections have been determined for the elements Cu, Ge, As, Br, and Rb at 16.896 keV.
• Fluorescence yields have been determined for the elements Cu, Ge, As, Br, and Rb.
• Results have been compared with results from experimental and theoretical studies.

K   shell X-ray production cross-sections (σKασKα and σKβσKβ) 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 (ωKωK) 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.
