Relativistic kinematic

We want to derive the how the energy of detected neutron depends on energy of incoming photons

[math] E = T + m[/math]

[math] E = p^2 + m^2[/math]

writing four-vectors:

[math] p_{\gamma} = \left( T_{\gamma},\ T_{\gamma},\ 0,\ 0  \right) [/math] 

[math] p^{\mu}_{\gamma} + p^{\mu}_{D} = p^{\mu}_{p} + p^{\mu}_{n} [/math]
[math] p^{\mu}_{\gamma} + p^{\mu}_{D} = p^{\mu}_{p} + p^{\mu}_{n} [/math]
