Answer #1

Line source is an infinite homogeneous medium consider an isotropic line source (infinite along z-axis) of strength So, (per centimeter per second) located at r = 0. The diffusion equation is where is the neutron diffusion length. The general solution of equation (1) is , where I0 and K0 are the modified Bessel functions of order zero of the first and second kind, respectively. The physical requirement for a finite solution at large r requires that A = 0. The source condition is Line source is an infinite homogeneous medium consider an isotropic line source (infinite along z-axis) of strength So, (per centimeter per
