Popis:	is a function of n and of the arrangement of the electrons in the atoms, sin b b2 sin2 0 and includes the Debye temperature factor e x2 . F, which is called the "atomic structure factor," approaches the number of electrons in the atom at small angles of reflection and theoretically should become equal to this number when sin 0 = 0. All of the unknown quantities in the above expression except F may be measured, so that F may be calculated. Since the measurements reported in this note are only relative, we may dispense with the part of (1) which does not enter directly into the determination of the relative intensities. We then have
