Description


              The effective number of electrons in the crystal unit cell
               contributing to F(000). It may contain dispersion contributions,
               and is calculated as

               F(000) = [ sum (f~r~^2^ + f~i~^2^) ]^1/2^

               f~r~ = real part of the scattering factors at theta = 0
               f~i~ = imaginary part of the scattering factors at theta = 0
