Abstract : Using Dirac's theory of dispersion, the probability of the simultaneous emission of two light-quanta is calculated. A definite probability is calculated that an excited atom will emit its excitation energy in two random amounts, if the sum of the energies is constant. If light of frequency less than the excitation frequency is incident on the atom, double emission can still occur. Conversely, the process is considered in which two quanta, the sum of whose frequencies is equal to the excitation frequency, collaborate to excite the atom. Further, the behavior of an atom which can emit light towards colliding particles spontaneously is investigated. Lastly, an attempt is made to clear up anomalies in the spectral line intensities caused by fast-electron collisions on the basis of double processes. (Author)
