Homework Statement
Consider a particle (which mass is [tex]m[/tex]) and the following unidimensional potential:
[tex]V(x)=\begin{cases}+\infty & x<0\\ -V_0 & 0<x<a\\0 & x>a \end{cases}[/tex]
Let [tex]E[/tex] be positive. Find the spatial autofunction.
Homework Equations
I'm convinced that I have to use Schroedinger's equation.
The Attempt at a Solution
I found:
[tex]\psi(x)=\begin{cases} 0 & x<0 \\ A\sin{lx}+B\cos{lx} & 0<x<a\\ C\exp{ikx}+D\exp{-ikx} & x>a\end{cases}[/tex]
where [tex]k=\frac{\sqrt(2mE)}{\bar{h}}[/tex] and [tex]l=\frac{\sqrt{2m(E+V_0)}}{\bar{h}}[/tex].
Is this correct?
