Thank you for your help! I am sorry, but I have never learned Latex and I am afraid I won't do it over night... I do not quite undestand why I am wrong and how it would be correct... if I integrate HΨ=EΨ, over a Interval from -e to e and then look at the limit of e to 0 I came to Ψ2(0)'...

And also thank you for this recommendation! The "Dirac Comb" seems really interesting!

First of all thank you for your help, I really appreciate it! If I apply the said and integrate the Schrödinger equation I come to ψ2(0)' - ψ1(0)' = h^2/2ma and the same for x=a, but with Ψ3 and ψ2. Where "h" represents h bar, but I do not know how to write it here. But from there on, how do...

You mean like, that the wavefunction and its derivative need to be continues at the "peaks"? I tried that and just came to 0=0, which i could not really use...

First of all thank you for you answer! But I want to solve the problem in general, since i can then apply it to future problems, so I got the three regions 1: x<0 A⋅exp(ikx) +B⋅exp(-ikx) ; 2: 0<x<a C⋅exp(ikx) +D⋅exp(-ikx) ; 3: a<x F⋅exp(ikx). But now I don't know, how I get a general solution to...

Summary:: I have a problem with a particle, which gets scatterd at a double delta-potential Hello, I am really stuck with the floowing problem: A particle moves from the left along the x-axis and gets scatterd at a one-dimensional potential V(x)=a[dirac delta of x) +b [dirac delta of x-c]...
