Задача 60270.

In the annihilation of a neutron and anti-neutron formed by two identical n-meson (quanta of the nuclear field). To determine the energy of each of p-meson, if the kinetic energy of the particles to the annihilation was negligible. The mass of the neutron rest is 1.675 * 10 ^ -27 kg.

Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
