A quantum mechanical particle with mass [tex]m[/tex] and energy [tex]E[/tex] approaches a potential drop from the [tex]-x[/tex] region, where the potential is described by:

[tex]V(x)=\left\{\stackrel{0 textrm{if} x\leq 0}{-V_0 textrm{if} x> 0}[/tex].

What is the probability it will be reflected by the potential?

2. Relevant equations

Incident Wave: [tex] \Psi (x,t) = A e^{k x - \omega t} \textrm{where} k= \sqrt{2 m D} /2 [/tex]

3. The attempt at a solution

I want to say 0, but that's without doing the math on it. The continuity equations yield 3 unknowns (A, B, C
