23. The precise derivation of this N exciton result will be given elsewhere. The reader questioning this result can stay with N = 2.
24. This TO corresponds to processes in which two excitons, out of N, go to (i, j) ≠ 0. It is N times smaller than the lifetime which enters the exciton linewidth and corresponds to have one exciton, out of N, going from 0 to i ≠ 0.
