Q: Fission reactors and cyclotrons tend to produce different kinds of isotopes.

Fission reactors and cyclotrons tend to produce different kinds of isotopes. A reactor produces isotopes primarily through neutron activation; thus, the isotopes tend to be neutron-rich (high neutron-...

Q: Why is a slow neutron more likely to induce a nuclear reaction

Why is a slow neutron more likely to induce a nuclear reaction (as in neutron activation and induced fission) than a proton with the same kinetic energy?

Q: Why can we ignore the binding energies of the atomic electrons in

Why can we ignore the binding energies of the atomic electrons in calculations such as Example 29.4? Isn’t there a mass defect due to the binding energy of the electrons?
