Proton induced L and L-subshell X-ray cross-sections in Sm and Yb at 1–2.5 MeV

L and L-subshell X-ray production cross-sections for protons on Sm and Yb have been measured in the incident energy range of 1–2.5 MeV. The values obtained agree with data available in Sokhi and Crumpton [R.S. Sokhi, D. Crumpton, At. Data Nucl. Data Tables 30 (1984) 49] and Orlic et al. [I. Orlic, C.H. Sow, S.M. Tang, At. Data Nucl. Data Tables 56 (1994) 159] and the uncertainties are less than 12%. The data are compared with predictions of the modified plane wave Born approximation by introducing corrections for energy loss (E), Coulomb deflection (C), perturbed stationary state (PSS) and relativistic (R) effects which is the so-called ECPSSR model.
