Using the transport equation for a non-multiplying system and homogeneous assembly, derive the integral form of transport equation using the method of characteristics. What do you understand by "Optical path length" of the medium?
The transport equation for a steady-state, non-multiplying, and homogeneous system without an external source is: [ \vec{\Omega} \cdot \nabla \psi(\vec{r}, \vec{\Omega}, E) + \Sigma_t \psi(\vec{r}, \vec{\Omega}, E) = \int_{4\pi} d\Omega' \int_0^\infty dE' , \Sigma_s(E' \to E, \Omega' \cdot \Omega) \psi(\vec{r}, \vec{\Omega}', E') ] For simplicity, consider monoenergetic neutrons and no scattering. The equation reduces to: [ \vec{\Omega} _____ _______ _____ ____ __________ ____ _____ ________ _______ __________ __________ _____.
