Physics · Quantum Mechanics
Consider a particle on a ring that is perturbed by interacting with an applied electric field (E) with the perturbation being H' = μE cos(φ), where μ is the dipole moment. The energy levels correct up to first order are:
- 1m ℓ 2 h 2 2I✓
- 2m ℓ 2 h 2 2I + μE 2π
- 3m ℓ 2 h 2 2I - μE 2π
- 4m ℓ 2 h 2 2 - μE π
Correct answer
m ℓ 2 h 2 2I
