The well is set up exactly like this https://www.physicsforums.com/showt...ential+barrier+inside+an+infinite+square+well. It is basically a infinite potential well with a barrier in the center.

Basically I've got solutions for regions 1, 2 and 3, found some allowed energy levels. In region one we have Asin(k1x) and in region 3 I have Dsin(k1x), when I use the continuity conditions to solve for the constants I find that A=-D. This means that when I plot the wave functions I end up with equal amplitudes on either side of the barrier. I would have thought that the amplitude in region three is smaller than the amplitude in region one. Can anyone tell me which is correct?

My apologies for not having it in the normal form but I thought because I'm not asking for help with a question but merly asking whether my result is feasible this form makes more sense. Also my apologies for my lack of latex but for some reason it wasn't working :-(. Sorry this is my first post (if you hadn't already guessed! ;-)
