FIGURE 8.10
The amplitude of figure 8.9, with positive 4-momentum antiparticles replaced
by negative 4-momentum particles.
FIGURE 8.11
The amplitude of figure 8.10 redrawn so as to obtain a reaction in which the
initial state has only ‘ingoing’ lines and the final state has only ‘outgoing’
lines.
FIGURE 8.12
One-photon exchange amplitude for the process of figure 8.11.
