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.

May19 awarded Supporter Aug4 awarded Nice Question Aug4 comment Where the angular momentum has gone?This was asked by one of my friends, so I do not really know.. Aug3 asked Where the angular momentum has gone? Mar18 comment How to solve this Schrödinger equation?@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. Mar18 comment How to solve this Schrödinger equation?I found out that I need to make the part $rr_{0}$ 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. Mar18 accepted How to solve this Schrödinger equation? Mar18 accepted What is the possible potential? Mar18 comment What is the possible potential?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? Mar18 awarded Editor Mar18 revised What is the possible potential?edited title Mar18 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. Mar18 asked What is the possible potential? Mar18 comment How to solve this Schrödinger equation?I think there is something very wrong in my computation as my result turned out to be 0. Mar18 comment How to solve this Schrödinger equation?@David Zaslavsky♦:hi, can you give me some hint how to find $V_{0}$? I found I am stuck again... Mar17 awarded Scholar Mar17 comment How to solve this Schrödinger equation?hi, so the energy at the bound state is not positive? I am very surprised. Mar17 awarded Student
