I will go through section 3.5 on The Probability Current.
On Wednesday we will describe a number of scattering and bound-state problems. Try to set up, on your own, the solution of the Schrodinger for a square well potential. I.e., . And . Treat a plane wave incident from the left with an energy E.
Here are some nice pics of examples of potentials:
