Hi there, I was hoping someone could maybe give me a hand with sketching eigenfunctions (although I reliase it can be difficult over the net!). I we have a particle at n=2 inside a finite potential well but we have a potential barrier in the middle of it, how do we draw this (the particle has energy lower than the sides of the potential well and lower than the potential barrier)? I have exponential decay into the sides of the well and I have exponential decay going through the potential barrier, but I'm unsure of how the wave itself should look. I know it will only have one node which is fine, but my problem is is there one node at each side of the step or just one for the entire way across the finite well?(adsbygoogle = window.adsbygoogle || []).push({});

I'm sorry I can't post up a picture or anything but I've just discovered that my scanner has mysteriously broken and heads are about to roll here. Not a happy bunny.

Anyway, any help would be much appreciated. Thank you.
