    Abstract:

    The method of steepest descent applied to the evaluation of multiphonon transition probabilities is discussed, especially in relation to multi-frequency models. It is shown that the saddle points correspond to a most probable distribution for the phonons. The variation of the phonon distribution with physical parameters and its effects on multiphonon transitions are discussed.
