Threshold for pi meson production* A high energy photon (γ-ray) collides with a proton at rest....
Homework Answers
Minimum energy of photon should be such that the sum of rest mass energy of proton and energy of photon in reactant side must be equal to sum of rest mass energies of proton and neutral pion on product side. However if the difference between reactant and product quantities is positive the reaction is possible and the energy difference is transmitted as kinetic energy in the products.But if this difference is negative then reaction would not be possible. Therefore if minimum energy of photon is E to occur this reaction then,
E + 938 = 938 + 135 MeV,
E = 135 MeV

In addition to its rest energy, a moving proton (p') has kinetic energy. This proton collides with a stationary proton (p), and the reaction forms a stationary neutron (n), a stationary proton (p), and a stationary pion (π+), according to the following reaction: p' + p → n + p + π+. The rest energy of each proton is 938.3 MeV, and the rest energy of the neutron is 939.6 MeV. The rest energy of the pion is 139.6 MeV....

The discovery of the antiproton p (a particle with the same rest energy as a proton, 938 MeV, but with the opposite electric charge) took place in 1956 through the following reaction: p + p → p+p+p+¯ p, in which accelerated protons were incident on a target of protons at rest in the laboratory. The minimum incident kinetic energy needed to produce the reaction is called the threshold kinetic energy, for which the final particles move together as if they...
