Solve problem 39 considering the sphere is located in an
infinite medium made up of water.
An isotropic point source emitting So
neutrons/s is placed in the center of a bare sphere of radius R. The
sphere is made up of carbon (L2 = D/_a).
Show that the general solution for flux inside the sphere is given by:
where C1 and C2 are constants of integration.
Apply the boundary conditions and find the neutron flux anywhere at r = R/2.
[Hint: Start with Equation VIe.2.14 and make a change of function; _=
