(A -5) 
It can be shown that the integral termis 0(€) compared with the 
first term. 
By using (A-2), (A-3), (A-4) and (A-5), we can now write 
ye Ae ikx =y  Nk(k = 2» ) o*(ik) 
@(x,y,z) = - = nn 
4 - 00 Vk(k - 27) 
0 \ k(2v -k) 
o* (k) 
[oe) Pl ba) 
i - k(k - 2 
; i ve eikx y ( v ) 
2v k(k - 2» ) 
+ higher order terms 
This expression can be rewritten as Eq. (17).
