Barrier in an infinite well

  1. Aug 20, 2012 #1
    Hello people, I'm trying to plot probability distributions from the given potential numerically.
    These are the results (particle coming from the right)


    What I want to know is why does the green curves (n=1) have higher probability at the left of the barrier? Why not the right(as the other curves)?

    Or if my results are completely wrong?

    Can anybody analyze my results, please.....

    What do you mean by "particle coming from the right"? If you have infinite barriers on both the left and the right, then you are presumably calculating the energy eigenfunctions, and these should be either symmetric or antisymmetric about the center.

    sorry for the question, I have found my fault.
