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.
