The Hamiltonian for a two-electron atom is:
where ℏ is the reduced Planck constant, m is the electron mass, e is the elementary charge, and r is the distance between the electron and the nucleus.
where a_0 is the Bohr radius.
H = -ℏ²/2m (∇₁² + ∇₂²) - Ze²/r₁ - Ze²/r₂ + e²/r₁₂
The Hamiltonian for a one-electron atom is: quantum mechanics of one- and two-electron atoms pdf
H = -ℏ²/2m ∇² - Ze²/r
Hψ = Eψ
Hψ = Eψ
where r₁ and r₂ are the distances between the electrons and the nucleus, and r₁₂ is the distance between the two electrons. The Hamiltonian for a two-electron atom is: where
where H is the Hamiltonian operator, ψ is the wave function, and E is the total energy.
The two-electron atom, also known as the helium-like atom, consists of two electrons orbiting a nucleus with atomic number Z. The time-independent Schrödinger equation for this system is: where H is the Hamiltonian operator, ψ is
