energies. For this reason, the Mo-L rather than the Mo-K
was used for the quantification, and the W-L or Ta-L
lines were not used at all. An example of a comparison
between results calculated from both the Mo-K<=<and the
Mo-If<line is given below.
The sample is the ternary alloy #17. As in the
previous example, a large probe size was used.

Note
: The ratio Lp/L0^3 .2265 was
used to reduce the
measured intensity of the Mo-L<< + Mo-LP peak. The Lp/L0*-
ratio was calculated from the MAGIC program.
The EDS results in Table 5.3 do not include values for
either the W or Ta quaternary additions. The analyses will
