with the lattice will excite vibrational modes and, therefore, emit a phonon by losing momentum equal to u = hνᵘ/s, where s is the speed of sound. We therefore have that p¹=p’¹+ u. The phonon is immediately reabsorbed by an electron with momentum p², having quantity of motion (q.o.m.) equal to p²+u
