or 1.5 x 10% atoms
Assume: the time spent in the gut is 77 hrs.
then, 7.3 x 101. atoms of Te!>* will have disintegrated
into 7.3 x 1011 atoms of 1132,
The average mean
of D* 1s about 0.55 Kev or 2.5
times that of 1431,
Thus, the energy equivalent to pt would be
(7.3 x 1077)(2.5) = 1.8 x 1022 atoms of1,
However, due to the short half-life of 132 (2.4 brs),
