Though hundreds of thousands had done their very best to disfigure the small piece of land on which they were crowded together, by paving the ground with stones, scraping away every vestige of vegetation, cutting down the trees, turning away birds and beasts, and filling the air with the smoke of naphtha and coal, still spring was spring, even in the town.

This was asked by one of my friends, so I do not really know..

@David Zaslavsky♦: Do you accept private email on such questions? I think I need someone's help in such question as my professor is not very understandable.

comment How to solve this Schrödinger equation?
I found out that I need to make the part $r<r_{0}$ to be like $A\frac{(e^{\sqrt{k}r}-e^{-\sqrt{k}r})}{r}$ to get finiteness at $0$ and at $r>r_{0}$ to be like $B\frac{e^{-\sqrt{k}r})}{r}$ to be 0 at $\infty$. However matching up the two as well as their derivative and assuming $E=0$ the result is $E=V_{0}=0$, I feel quite bad.

Hi, so the hint is if $\Phi(r,\theta,\phi)$ is an eigenfunction of $L_{z}$, then $V(r,\theta,\phi)$ is also an eigenfunction of $L_{z}$? Is this necessarily true?

comment How to solve this Schrödinger equation?
@David Zaslavsky♦: The problem for some unknown reason asked me to find $V_{0}$, my computation use wolfram alpha showed it to be 0, which sounds very unlikely because the problem said it can be measured in MeV.

I think there is something very wrong in my computation as my result turned out to be 0.

@David Zaslavsky♦:hi, can you give me some hint how to find $V_{0}$? I found I am stuck again...

hi, so the energy at the bound state is not positive? I am very surprised.
