Abstract: | K-shell ionization cross section measurements are reported for35Br,37Rb and39Y targets caused by protons over 300–400 keV energy range in 20 keV increment. The K-shell ionization cross sections (σ
k
l
) at different energies were deduced from the Kα and Kβ X-ray production cross sections which were obtained from X-ray yields of the Kα and Kβ transitions. The experimental values are compared with the calculated values of ECPSSR theory and empirical reference cross
sections. The resultant K-shell ionization cross sections are found to be in reasonable agreement with the ECPSSR theory.
The Kα/Kβ intensity ratios are also presented and compared with other experimental values and also with the theoretical one-hole values
given by Scofield. |
