The structure of platinum phthalocyanine

X-rays of atom i and is given, in the limiting case of all the electrons of atom i concentrated at the hypothetical center of the atom, by 

The electron diffraction method is based on the same principles as the X-ray method but, because of the charge on the electrons, their 

It is the latter application in which we are most interested The electrons are assigned a wave length according to the 

Thus a 1-volt electron has a wave length of 10 cm. and a 40 kilovolt electron, which is the usual velocity used, has a wave length 

The general form of the equation giving the dependence of the intensity Iq of the coherently (elastically) scattered beam of electrons on the angle of scattering d is identical with that
