Consider a point in space r(vector) where the flux is isotropic; i.e., equal numbers of neutrons move into solid angles d(omega) about every direction omega.(adsbygoogle = window.adsbygoogle || []).push({});

a) Show that the net current J(r) is zero

b) Show that the magnitude of the current in any direction is just one quarter of the scalar flux.
