Measurements of K-shell X-ray production cross-sections and fluorescence yields for Cr, Mn, Fe and Co elements

•KαKα and KβKβ X-ray production cross-sections have been determined for the elements Cr, Mn, Fe and Co at 8.735 keV.•Fluorescence yields have been determined for the elements Cr, Mn, Fe and Co.•Results have been compared with results from experimental and theoretical studies.

KαKα and KβKβ X-ray production cross-sections have been measured for the elements Cr, Mn, Fe and Co. Measurements have been carried out at 8.735 keV excitation energy by using secondary source. The values of K  -shell fluorescence yields ωKωK have been measured for the same elements. The results obtained for K X-ray production cross-sections and fluorescence yields have been compared with theoretically calculated values and other available semi-empirical values.
