“y Contributions at Various Times
The fh and Y contributions for various times are shown in the
following table:
1.
The total
activity is taken as 10° d/m at each
2.
The isotepes and their percent contributions to
specified’ time after fission.
total activity are taken from the data of Hunter
and Ballou.
3.
and YT energies and the decay schemes from all
otopes are taken from NBS Circular 99, and supple-
ments, and Nuclear Science Abstracts through December
1955.
