本文概述了描述绝缘晶体非定常激发态的一般方法。在一般情况下，含时波函数通过一个简单的生成函数隐式给出。在最近邻近似中，解可以用贝塞尔函数显式给出。研究了理想化晶体表面对激子传播的影响。激子表现得好像被表面排斥。
A general method for the description of nonstationary excited states of an insulating crystal is outlined. For the general case, the time‐dependent wave function is given implicitly by means of a simple generating function. In the nearest‐neighbor approximation, the solution can be given explicitly in terms of Bessel functions. The effect of an idealized crystal surface on exciton propagation is examined. The exciton behaves as though repelled by the surface.
