AW Singles Prob Y88 2015

Problem description:

The singles spectra production for the initial Y-88 activity is off by a factor of 2.

Right now the high energy line is a factor of 2 higher.

$N(\frac{1836}{898}) =\frac{\frac{ UN(1836)}{.31}}{ \frac{UN(898)}{.78}}=\frac{5}{2} \frac{UN(1836)}{ UN(898)}=1$

Ratio$\equiv \frac{UN(1836)}{ UN(898)}=\frac{2}{5} = 0.4$
