## Homework Statement

I am working on 6.16 at the following site:

http://mikef.org/files/phys_4241_hw14.pdf [Broken]

I think that the solution given is given is wrong. I can get part a), however, I am just getting stuck on part b). So, the wavefunction in r < r_0 is

R(r) = A/r sin(k_1*r)

and the solution in r > r_0 is given by

R(r) = B/r exp(-k_2*r)

I have no idea how t do what they are asking in part b) since we have three unknowns, A, B and V_0 and only two equations: namely continuity at r_0 of R and R'. Is there something that I am missing?
