Polariton effects in the resonant emission of KI and RbI - Nouailhat, A.; Guillot, G.; Mercier, E.; Van Khiem, T. (Elsevier)
We have observed the narrow resonant emission in KI and RbI crystals under electron irradiation. Its properties as a function of the penetration depth of electrons in the crystal, as well as estimated lifetime and half-width, can be interpreted in the point of view of the polariton theory.
