Question

приведите примеры реакций ядерного синтеза

Answer 1

D+D -> He3 + n + 3,3 МэВ (т.е. образуется изотоп Гелий-3)
D + He3 -> He + p + 18,3 МэВ

D + D -> T + p + 4 МэВ
D + T -> He + n + 17,6 МэВ

Это два пути образования гелия из водорода.

Но есть пути и дальше.

Nuclear Fusion Reactions and Examples

Nuclear fusion reactions involve the combination of atomic nuclei to form a heavier nucleus, releasing a large amount of energy in the process. This process is the source of energy in stars, including our Sun. Here are some examples of nuclear fusion reactions:

1. Proton-Proton Chain Reaction: In the core of the Sun, hydrogen nuclei (protons) undergo a series of fusion reactions to form helium. The primary reaction is the proton-proton chain reaction, which involves the following steps: - Two protons combine to form a deuterium nucleus (one proton and one neutron) through the weak nuclear force. - The deuterium nucleus combines with another proton to form a helium-3 nucleus. - Two helium-3 nuclei combine to form a helium-4 nucleus and release two protons. - The overall reaction can be represented as: 4 protons -> helium-4 + 2 positrons + 2 neutrinos + energy.
