The question of the multipole character of the elementary radiator [ 1939 ]
“A more detailed discussion of this point seems to be justified by the fact
that although in two previous papers the authors had given a very
exhaustive theoretical treatment of wide-angle interferencees, … , they
never recognized or at least never mentioned the experimental difficulties
existing in this respect. As a matter of fact, their treatment is based upon
the assumption that the light source is stricly point-like. Therefore the
influence of the shape and of the finite dimensions of the light source had
not been taken into consideration, though these are the most important
experimental factors which generally prohibit the realization of wide-angle
interferences.”
