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
