following paragraphs outline the procedure by which we obtained our set
of preferred yields.
The most nearly complete set of yield data is given'by Bidinosti
et al. (29). Nearly all of these yields were normalized to each other
mass-spectrometrically, and the number of fission product atoms produced
was determined absolutely. Exceptions were the normalization of Ru
yields to Mo yields using radiometric data and the adjustment of the
Zr-Mo-Ru group of yields to force the light mass peak to total 100%.
These authors state that, when they forced their measured and interpo-
lated yields in the heavy peak to total 100%, the absolute number of
fission product atoms was 2-4% greater than that calculated from flux
monitors which they had included in their experiments.
We have reduced their reported absolute yields by 3%, in
agreement with their flux measurements, and find that the sum of the
measured and interpolated yields is then 100% for each peak. Obviously
this kind of normalization depends somewhat on how one interpolates to
*
obtain missing yields. We have used the radiometric yields of Steinberg
and Glendenin (3) to obtain some of the missing yields, especially in
the valley, and have "reflected" measured yields from one peak to the
other to obtain the shape of the mass-yield curve where several yields
were missing. The reported values from Refs. 4, 18, and 27 have been
* We chose not to use the radiometric yields of Santry and Yaffe (30)
because several of their values deviate widely from the mass-
spectrometric data, and it was not possible to correct their data
in any reasonable way to agree with the mass-spectrometric results.
