Angular neutron flux refers to the distribution of neutrons in a reactor in terms of both their position and direction. It is defined as the number of neutrons passing through a unit area per unit time, per unit solid angle. Mathematically, it is represented as \(\Phi(\vec{r}, \hat{\Omega})\), where \(\vec{r}\) __________ ______ ___ _________ ______ ________ ______.
