Measurement of K X-Ray Cross-Sections for Elements with 22 â‰¤ Z â‰¤ 42 at Liquid Nitrogen Temperature

X-ray production cross-sections for K a and K b X-Ray lines measured for Ti, V, Fe, Ni, Cu, Zn, Nb and Mo at a photon excitation energy  of 59.5 keV at the liquid nitrogen temperature (-196 0 C ) using a high resolution Si(Li) detector. The values obtained were compared with the experimental values at ambient temperature (laboratory conditions) and theoretical values. The experimental values at liquid nitrogen temperature are smaller than that of the values at ambient temperature. No variations in the s K a and s K b fluorescence cross-sections at liquid nitrogen temperature (-196 0 C) are observed.
