In many cases, a parent nucleus, level 1, decays at a rate R_{12}
into a daughter, level 2, that is not stable. The daughter can proceed
with decay to level 3 with a rate R_{23}. In this section, R_{23}=2*R_{12} as in Figure 15-13
in the text.

Section 3 Exercises:

Is the number of nuclei a constant? If so, what is it?

Is the decay of the parent exponential? Measure the decay rate
of the parent.

The number boxes above allow you to change the different rates. Once
you have entered the new rates, click "Set". A copy of the graph
window may be made by right-clicking in the graph window. This window is
static and may then be used for comparison purposes with a graph with new rates.

Sketch what plots of N_{2} and N_{3} would look like if R_{23}
>> R_{21}. Explain.
