The authors calculated values for the ratios of the double-electron to
main-line strengths with their corresponding excitation energies for
the LN4,5 edges of elements found in the sixth row of the Periodic Tab
le. In addition, the approximate analytical forms for the relative int
ensities in terms of monopole matrix elements are also given. A compre
hensive view of double-electron processes which affect extended x-ray-
absorption fine structure analysis of elements in the sixth row is obt
ained.
