Homework Statement
Two-electron Wavefunction: ψ(r1,r2,r12) = exp(-Ar1-Br2-Cr12), r12 = |r1-r2|
A, B, and C are coefficients
Calculate <ψ|δ(r12)|ψ> and <ψ|δ(r1)|ψ>
Homework Equations
NO
The Attempt at a Solution
<ψ|δ(r12)|ψ>
= ∫∫dv1dv2ψ2(r1,r2,r12)δ(r12)
=4π∫dr2ψ2(r2,r2,0)
<ψ|δ(r1)|ψ>
= ∫∫dv1dv2ψ2(r1,r2,r12)δ(r1)
=4π∫dr2ψ2(0,r2,-r2)
Could you tell me where I am wrong?
Best regards.
