5.2.1.1 Solution hmola-a

**Question:**

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

**Answer:**

The repulsive potential is the term

and when
