Step 1
The Coulomb barrier is the energy barrier due to electrostatic repulsion between positively charged nuclei, and the fusion energy release is the energy produced when two nuclei fuse. Show more…

Calculate (1) the temperature necessary to overcome the Coulomb barrier and $(2)$ the fusion energy release in a gas of: (a) ${ }^{16} \mathrm{O}$ : (b) ${ }^{12} \mathrm{C}$ : (c) ${ }^{34} \mathrm{Mg}$; (d) ${ }^{14} \mathrm{~N}$ : (e) ${ }^{10} \mathrm{~B}$.
Some stars, in a later stage of evolution, may begin to fuse two $^{12}_{6}$C nuclei into one $^{24}_{12}$Mg nucleus. ($a$) How much energy would be released in such a reaction? ($b$) What kinetic energy must two carbon nuclei each have when far apart, if they can then approach each other to within 6.0 fm, center-to-center? ($c$) Approximately what temperature would this require?
