# How tell bound or scattering state in double Dirac delta function well?

I'm solving problems from "Introduction to Quantum Mechanics" by David J. Griffiths. In question 27 of second edition of the book, there is a question that states:

"Consider the double delta-function potential, $V(x)=-\alpha[\delta(x+a)+\delta(x-a)]$ where $\alpha$ and $a$ are positive".

How do I tell if this is a bound or scattering state?

• This is a potential. You have not written down a state. – By Symmetry May 29 '18 at 11:04
