Chapter 43, Problem 43.76PP

To determine

A minimum kinetic energy the protons need to make the reaction go, in the reaction energy that produced by ${}^{131}\text{I}$ from the following options:

1. (a) No, because the proton has a smaller mass than the neutron.
2. (b) No, because the total initial mass is smaller than the total final mass.
3. (c) Yes, because the proton has a smaller mass than the neutrons.
4. (d) Yes, because the total initial mass is smaller than the total final mass.
