【Abstract】 In this paper, the properties of a slow exciton in a polar crystal are discussed. A perturbation method developed by Haga is used. In the approximation that we ne- glect the interaction of phonons of different wave vector in the recoil effect, the wave function in the second approximation is calculated, moreover the electrostatic poten- tial is also calculated.更多还原
