Exact and approximate energy spectrum for the finite square well
... equation. We obtain the spectrum analytically as the solution to a pair of parametric equations and algebraically using a remarkably accurate approximation to the cosine function. The approach is also applied to a variety of other quantum wells. © 2006 American Association of Physics Teachers. 关DOI: ...

It also gives totally symmetric or anti-symmetric multi-body wave functio ...
