${ }_{94}^{232} \mathrm{Pu}$ Is Unstable $A$ Is About 1 ${ }_{90}^{230} \mathrm{Th}$

Multiple Choice

${ }_{94}^{232} \mathrm{Pu}$ is unstable. Which of the following nuclei might be a possible outcome of a single-step decay process from this nucleus? (Hints: The optimal NIZ ratio for this $A$ is about 1.53. This nucleus has two possible decay outcomes, but perhaps only one is listed. If you are using the back of the book to respond, you can indicate multiple responses by pointing to more than one letter.)

A) ${ }_{90}^{230} \mathrm{Th}$
B) ${ }_{92}^{230} \mathrm{U}$
C) ${ }_{92}^{228} \mathbf{U}$
D) ${ }_{95}^{232} \mathrm{Am}$
E) ${ }_{95}^{231} \mathrm{Am}$
F) None of the above (specify an outcome)
