Hello, and in this question here, we're asked to determine energy released in this nuclear fusion, where we have one proton fusing with a deuterium to produce a helium -3 isotope and a gamma -ray.
00:14
So to determine the energy release in this nuclear fusion, we're going to use conservation of energy.
00:22
And the initial energy, okay, well, the initial energy, which is the rest -mass energy of the hydrogen, plus the rest mass energy of the deuterium, where we use a subscript d for deuterium, is equal to the rest mass energy of the helium plus the energy that is released to the environment.
00:44
And this energy releases in the form of the kinetic energy, the helium, and the gamma ray.
00:50
So we can rearrange to get the energy as equal to the mass of the hydrogen, plus the mass of the deuterium minus the mass of the helium times c squared.

And these are the three masses that i've included here and you can get these from the appendices in the back of the book...
