Verify that the repulsive potential between the electrons is infinitely large when the electrons are at the same position.
Note: You might therefore think that the wave function needs to be zero at the locations in six-dimensional space where
Coulomb hole.” But the truth is that in quantum mechanics, electrons are smeared out due to uncertainty. That causes electron 1 to “see electron 2 at all sides, and vice-versa, and they do therefore not encounter any unusually large potential when the wave function is nonzero at
The repulsive potential is the term
