Chapter 12, Problem 12.19E

Interpretation Introduction

Interpretation:

The validation of the statement that the equation 12.7 is symmetric with respect to exchange of the two electrons is to be stated.

Concept introduction:

The property of wavefunctions in which the labels of electrons can be interchanged implying that the two electrons are exchangeable is known as antisymmetric. This property can be mathematically written as,

$\Psi \left(1,2\right)=-\Psi \left(2,1\right)$

The wavefunction that remains the same on the interchange of electrons $1$ and $2$ is known as a symmetric wavefunction.
