# Double delta-function potential

My session expired while typing this post, so this is my second attempt at typing it. I *always* forget to paste into notepad before submitting these darned things.

## Homework Statement

Problem 2.27, Griffiths.

Given two delta potential wells at +a and -a, determine the number of bound states, find their associated energies, sketch the wave functions.

## Homework Equations

$V(x) = -\alpha\left[\delta\left(x+a\right)+\delta\left(x-a\right)\right]$

## The Attempt at a Solution

This is the first problem in the book where I really do not know where to begin. I know that the answer has to be in some form of exp(kt) where k is sqrt(-2*m*E)\hbar.

I vaguely understand the book's process for the logic behind constructing the wave function for a single delta potential well, but clearly not well enough.
