Abstract
Some properties of excitons in polar crystals are studied. The effecti ve Hamiltonian of the exciton in polar crystals is derived by a pertur bation method. If we consider the interaction between phonons of diffe rent wave vectors in the recoil process, the influence on the effectiv e potential between electron and hole, the self-trapping energy, and t he self-trapping condition are discussed.
