Consider pairing of clectrous mediated via phonous. (i) Draw Feynman diagrams of two processes in which an electron with momentum +k releases a phonon with momentum q which is later reabsorbed by another electron with momentum -k, and in the other, electron with -k releases phonon which is later re-absorbed by the electron with +k.
