Proton induced L-shell X-ray production cross-sections for Pb in the energy range 225–400 KeV

Abstract

The L-shell X-ray production cross-sections in lead (Pb) by proton impact over the energy range 225–400 keV, with an interval of 25 keV, have been measured. The thick target X-ray yields have been obtained using a HPGe detector. The experimental results for σ L 1 , σ L α , σ L β and σ L γ have been compared with perturbed stationary state theory with relativistic (R), energy loss (E) and Coulomb (C) corrections (ECPSSR theory). The comparison of L α , L β and L γ , X-ray production cross-sections shows a fairly good agreement, except at the lowest energy. The L 1 X-ray production cross-sections are higher by ≈ 20–30% than their theoretical estimates.
