For a semi-infinite crystal,the expression for wave field of X-ray reflection,Dh is de-rived by the retarded Green function G(r). For a crystal with finite thickness it can be solred using G(r) and advanced Green functions Ga as well.These results have been corn.pared with previous results obtained by using Riemann function or Fourier integral andit is found that they are in agreement quite well.
