Question

1. An infinite planar source emitting S neutrons/cm'-sec is placed between infinite slab of beryllium and graphite of thickness a and b, respectively, as shown in the picture below. Derive lim)S sides of the source, this problem is not symmetric and the source condition valid. The appropriate boundary conditions for this problem are is not (i) lin,-ald(x > 0)-φ(x < 0)]-0 Condition (i) states, in effect, that ф is continuous at the source, whereas (ii) accounts for the neutrons emitted from the source.] Planar source emitting S neutrons/cm2- sec at x Air Beryllium Graphitc Air Figure 5.9 Infinite planar source between two finite slabs of materia
