7. This expression is obtained by combining an idea of multipole expansion with the so-called operator equivalent technique [K.W.H. Stevens, Proc. Phys. Soc. London Sect. A 65, 209 (1952)]. The same treatment can be also found in Amara and Morin's paper [M. Amara and P. Morin, J. Phys. Condens. Matter 10, 9875 (1998)].

10. 2) is finite, higher-order components in multipole expansion, which are even with respect to both x and y and change their signs by switching x and y, could be also finite. The observed condition of diffraction is, in fact, not inconsistent with the existence of such higher-order terms.
