摘要
对于一维散射给出了透射振幅的格林函数表示 ,对于三维散射近似给出了散射振幅的格林函数表示 .利用散射振幅的格林函数表示 ,更一般性地说明了一维和三维情况下散射振幅的极点与束缚态能级的关系 .
The transmission amplitude expressed by Greens functions is derived exactly for the case of one dimension,and the scattering amplitude for the three dimension case is also given approximately by Greens functions.With the analytical expressions of this scattering amplitude,we can illustrate the relation of the poles of the scattering amplitude and the bound states in a more generated way.
