Question:
Consider a particle of energy \(E\) moving in a one-dimensional potential well \(V(q)\), such that
\[
m \hbar\left|\frac{d V}{d q}ight| \ll\{m(E-V)\}^{3 / 2}
\]
Show that the allowed values of the momentum \(p\) of the particle are such that
\[
\oint p d q=\left(n+\frac{1}{2}ight) h
\]
where \(n\) is an integer.
