M i ( i = 1–5) subshell fluorescence and Coster–Kronig yields for elements with 67 ⩽ Z ⩽ 92

Abstract

A complete set of the M i ( i = 1–5) subshell fluorescence and Coster–Kronig (CK) yields has been generated by interpolation for elements with 67 ⩽ Z ⩽ 92 from the Dirac–Hartree–Slater (DHS) model based values tabulated for a limited number of elements, considering the cutoff/onset of different CK transitions in accordance with the CK transition energies evaluated in the present work. The CK transition energies have been deduced from tabulated values of the Dirac–Hartree–Fock–Slater model based neutral atom binding energies [K. Huang, M. Aoyagi, M.H. Chen, B. Crasemann, H. Mark, At. Data Nucl. Data Tables 18 (1976) 243] and the L i ( i = 1–3) subshell CK transition energies [M.H. Chen, B. Crasemann, K. Huang, M. Aoyagi, H. Mark, At. Data Nucl. Data Tables 19 (1977) 97] in order to establish the cutoff/onset of different CK transitions at specific atomic numbers. A second set of the M i ( i = 1–5) subshell fluorescence yields have also been deduced using radiative widths computed from the Dirac–Fock (DF) model based X-ray emission rates, and the total widths reevaluated to incorporate the DF model based radiative widths in place of those based on the DHS model. Further, the CK-corrected ( ν i ) and average fluorescence ( ϖ M) fields, which are experimentally important, have been evaluated from the generated set of CK yields and two sets of fluorescence yields.
