SUMMARY
A high-energy proton can collide with a photon to produce a charged pion and a neutron, as described by the reaction p+ + ph → pion + n0. For a photon sourced from the cosmic microwave background with an energy equivalent to a temperature of 3 K, the minimum energy required for the proton to facilitate this reaction is calculated based on the rest mass energies of the neutron and pion. The left-hand side of the reaction must equal or exceed the energy of the right-hand side, necessitating precise energy calculations.
