comment how to solve this scaling equation
Sorry for being difficult but I am not able to get the ansatz from your final final equation. I am subbing in $x = log s - log b$. Is this type of scaling equation covered in any textbooks?

comment how to solve this scaling equation
thanks for the answer. The problem is tougher than I envisioned. I'm still working through what you wrote and I wasn't clear what your $f(x)$ is. Is that the same as $\psi$? Also it seems that s/b would shift x by -log b.

comment electron hole exchange
I figured it must have been something along those line. Any idea where I could learn more about this?
