I only want to know how I can normalize it using the Dirac delta function. That is all. I never said that i want to calculate the reflection or transmission coefficient.

Thx, but I know how normalization normally works :rolleyes: But not in this case: Free Particle and I HAVE TO use the DELTA FUNCTION.

How can i use the 2nd one this in this case? I have the wave function: psi(x) = A*e^ikx + B*e^-ikx with k = sqrt(2mE/h^2). I think I can take A = 1, but then i don't know how to continue.

Hello! I'm trying to solve some old exam exercises to prepare for my qm exam next week. Now I got a question I don't have any idea how to solve it. I hope somebody can help me: "The radial Schrödinger equation in the case of a 3D spherical symmetric potential V(r) can be written in the...

Hello! Can somebody tell me, how it is possible to normalize the wave function of a free particle using the Dirac delta function? Thanks!

I have another question to the same problem: In which situation can the eigenstates be degenerated?

Great! Thanks for this answer!

Hi! I read that in an 1D potential, the solution for the Schrödinger equation is always either symmetric or antisymmetric if the potential is a symmetric function: V(x) = V(-x). How can I proof this? Thanks, for ur answers!
