§10.73(ii) Spherical Bessel Functions
►The functions , , , and arise in the solution (again by separation of variables) of the Helmholtz equation in spherical coordinates (§1.5(ii)): …With the spherical harmonic defined as in §14.30(i), the solutions are of the form with , , , or , depending on the boundary conditions. Accordingly, the spherical Bessel functions appear in all problems in three dimensions with spherical symmetry involving the scattering of electromagnetic radiation. …5: 10.48 Graphs
