To quickly assess the difficulty of the text, read a short excerpt:
E, ... E. , ... . The bound states are charac- 1 n' J' terlzed by the requirement that the function vanish at r = R. Now consider that function which Is Identical with the J'th bound state solution for r S R and which Is a solution of the free wave equation for the energy E for r> R, with contlnuoiis value and slope at r = R. From \inlqueness, this amst be Identical with the scattering solution, which Is a multiple of BlnTk r + Tj(k. )3 In the external region. Since this must vanish at r = R, I...t follows that k R + Ti(k ) must be a multiple of n. J J To prove the equivalence of the two different definitions of k. , Eqs. (5. 2) and (5. 4), it must still be shown that the multiple of « is in fact J itself. To see this, we note firstly that by Levlnson's theorem. 13a Figure 1 {N> Z)ir N-fl N+2 A schematic plot of ^(k) a kR + T](k) versus k; ^(k) need be defined only for non-negative energies. Since there are N negative energy states, Le-vlnson's theorem gives ^(O) = Nrt. By Wigner's causal Inequality, d5(k)/dk > for any interval of k vhlch satisfies Jx ^ C(l^) - (J + 2)jt> where J is an integer, which, from the above dis- cussion, must be greater than N.
