Hello. Where is come from the heat (about 17,59MeV) from reaction deuteron + tritium -> Alfa + netron + Q although sum of substrates's mass is greater than sum of products's mass?
Fusion reaction deuteron + tritium

That is the point. The initial mass is larger - a small part of that stored energy is released in the reaction.Jasiu said:although sum of substrates's mass is greater than sum of products's mass?

I make mistake: products mass is greater (alfa - 4,02781u, neutron - 1,008665u, sum - 5,036465) than substracts (deuteron - 2,01410u, tritium - 3,016049u, sum - 5,03015u). Where is come from this energy?

It's wiki mistake about Alfa mass (https://en.wikipedia.org/wiki/Isotopes_of_hydrogen), here is the correct value - http://www.chem.uAlberta.ca/~massspec/atomic_mass_abund.pdf, be careful with data source. Now sum of products mass is 5,011268. The diffrence is 0.018882 ~ 17,59MeV). Agrees.

There is no mass of the alpha (note the spelling) particle in the article about hydrogen isotopes.Jasiu said:It's wiki mistake about Alfa mass (https://en.wikipedia.org/wiki/Isotopes_of_hydrogen)
The helium article has the right mass.

Yeah, you're right, my mistake.
