Given a delta function barrier located at x=0: V(x) = +a * delta(x)(adsbygoogle = window.adsbygoogle || []).push({});

If you have a particle incident from the left with E<0, what does the wave function look like??

I have trouble with this because I thought the particle energy needed to be greater than the minimum potential (E > Vmin) for you to get a solution.

I figure there are no bound states (only scattered states). But what does that mean for the wave function with E<0?
