18M.3.HL.TZ2.6b.ii
Two protons, travelling in opposite directions, collide. Each has a total energy of 3.35 GeV.
As a result of the collision, the protons are annihilated and three particles, a proton, a neutron, and a pion are created. The pion has a rest mass of 140 MeV c–2. The total energy of the emitted proton and neutron from the interaction is 6.20 GeV.
(b.ii)
The diagram shows the paths of the incident protons together with the proton and neutron created in the interaction. On the diagram, draw the path of the pion.
