Measurements of K- shell Production Cross-Section and Fluorescence Yield for Y Element

Abstract

K-shell X-ray production cross-section have been measured for Y element. 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 yield has been evaluated for Y element. The results obtained for fluorescence yield and K X-ray production cross-section has been compared with the theoretically calculated values and other available semiempirical fits values.
