Why it works[edit]

It works of course partly because the reactants, particularly the Tritium, are relatively massive relative to their electric charges, so there's more momentum to overcome the coulomb forces. Need a clear explanation of this and a source. Andrewa (talk) 07:44, 11 December 2020 (UTC)[reply]

Its not so much the higher mass. It is the effect of the stronger binding energy of ⁴He compared to the D and T nucleus. So a reference to the Bethe-Weizsäcker-formula that describes the mass and binding energy of a nucleaus should be inserted into the article. Robin Größle (talk) 09:14, 8 November 2023 (UTC)[reply]

Better stub cat?[edit]

Garnarblarnar, thanks for the better sub category. But it's not a chemical reaction, so that stub cat is badly named. I'm looking for a better one. Andrewa (talk) 07:51, 11 December 2020 (UTC)[reply]

Andrewa Thank you for the correction on part, I appreciate it. New one looks good. Garnarblarnar (talk) 08:09, 11 December 2020 (UTC)[reply]

Likewise. See wp:creed#2. Andrewa (talk) 08:20, 11 December 2020 (UTC)[reply]

PDF about Fusion[edit]

I recently dug through the SULI course and found a presentation covering DT fusion. Sungodtemple (talk) 14:14, 29 January 2021 (UTC)[reply]

B class?[edit]

@Andrewa: I've improved the article. I know it's at least C class but do you think it's B class yet? Sungodtemple (talk) 15:45, 16 February 2021 (UTC)[reply]

Definite improvement! There are four different assessments that should be visited. They may be different according to which WikiProject criteria are used.

I'm probably more interested in the importance, currently unassessed by either WikiProject. It would seem to me to be quite an important article to WikiProject Energy, for obvious reasons I think. Less so to WikiProject Physics.

I haven't been much involved in such assessments, so I'm on a learning curve here. Andrewa (talk) 21:00, 16 February 2021 (UTC)[reply]

Ok. I assessed the importance. I still have no idea what class though... Sungodtemple (talk) 13:04, 17 February 2021 (UTC)[reply]

Where does the energy comes from?[edit]

The article describes that the energy from the fusion comes from E=mc². But there is 1 electron, 1 proton, and 1 neutron from the Deuterium as well as 1 electron, 1 proton, and 2 neutrons from the Tritium on one side of the equation. On the other side, there is 2 electrons, 2 protons, and 2 neutrons from the Helium as well as 1 free neutron. Seems to me the masses are balanced. So what mass is converted to energy? Where does that energy comes from? Should be interesting to include that information in the article. Marchildon Sophia (talk) 07:03, 8 January 2023 (UTC)[reply]

Even with the same number of electrons, neutrons and protons there is a small mass difference. This is described by the Bethe-Weizsäcker-formula.

In other words, the ⁴He nucleus is stronger bound then the T and D nuclea. And binding energy is again correlated with mass by E=mc² Robin Größle (talk) 09:09, 8 November 2023 (UTC)[reply]
