Chapter 12, Problem 12.13E

Interpretation Introduction

Interpretation:

The six coordinates that are used to determine $r_{12}$ for the electrons in $\text{He}$ are to be identified.

Concept introduction:

In quantum mechanics, the wavefunction is given by $\Psi$. The wavefunction contains all the information about the state of the system. The wavefunction is the function of the coordinates of particles and time. The time-independent Schrödinger equation is represented as,

$\widehat{H}\Psi =E\Psi$

Where,

• $\Psi$ represents the wavefunction.

• $E$ represents the energy of the particle.

• $\widehat{H}$ represents the Hamiltonian operator.
