I Just to check Schrodinger equation with 2 electrons

Hi folks,

I just want to check I understand correctly the Schrodinger equation for two electrons.

https://en.wikipedia.org/wiki/Schrödinger_equation#Time-independent_equation

With control F you can find "two electrons atoms or ions" section.

Let's assume the wave function = x1 2+ x22 and let's test if it satisfies the differential equation. (Instead of position vector r y use only x in 1D and the Laplacian operator is just a derivative respect x):

E * (x12 + x22) = -h2 * (2/μ) + e2/4piε0 * (1/x2-x1 - Z ( 1/x1+1/x2)) * (x12 + x22)

In case this equation were true I would have found a solution, Is this correct?

This is very odd.

In 1D, you do not get that type of a central potential. You have to solve this in 3D if you want to keep that potential.

This demonstrates opening this thread was a good idea.

Do you know any book or thread were the 2 body problem is approached. Since I read it is not solvable I assume nobody is publishing failed attempts. I suppose mathematicians have tried very hard to solve this equation and maybe they don't know how to do it, but for sure they know a lot of ways not to solve it right?
