Abstract : This report contains a brief summary of research performed on optical and mechanical properties of solids, including energy transfer and photo-ionization. The topics discussed include core (X-ray) excitons, effects of magnetic fields on excitons in many-valley semiconductors, simultaneous and cooperative absorption of a photon and energy transfer, effects to be expected because of non-infinite vibrational relaxation rates, a new method for generating sum-rules, and some remarkable products thereof, the angular distribution of electrons in the photo-ionization of polyatomic molecules, and librons in solid N2.
