20. Here we can only mention c dd x = c dd y = c dd z, namely c dd - = 0, in the spherical geometry and non uniform density. The dipolar effect disappear in the geometry and density given by Gaussian form. However, we do not assume the Gaussian density, not discussing the Josephson oscillation under c dd x, y, z = 0.
