SINGLE-PHOTON ANNIHILATION AND ELECTRON-PAIR
... The energies of the quanta involved in the processes (1) must have not only a lower bound, but also an upper one. The upper limit of the energy of the quanta is determined by the obvious requirement i\ .<. l, where i\ = 1/w is the wavelength divided by 2rr, and l the mean distance between particles. ...
